![]() ![]() This material is listed as ‘Aluminum (generic)’. Material Propertiesįor my free-free mesh density tests I ran above, I was using the generic Elmer aluminum material. 2, and wait around 10 minutes for the answer. But if I wanted a more accurate answer, I could choose a finer mes size, like. If I had to get my answer in less than 3 minutes, I would chose a fineness of. But when you make your mesh finer, it takes longer to get the answer. ![]() In this case, if I wanted an answer that was accurate to within 1% convergence for modes 1-9, I need a mesh density of. Percent frequency error of each mode as is mesh made finer I solved for free-free tuning fork natural frequencies where I varied my mesh fineness from 1(coarse) to. When you go from a coarse to a finer mesh, you answer converges on stable value.īut the finer you make your mesh, the more time it takes to get an answer. Mesh Density and Solve Time, Free-Free Model: Modes higher than mode 6 will be seen in ‘real life’. The first 6 modes must be ignored because they are rigid body motion, where the part is moving along an axis, or rotating. I analyzed the tuning fork without holding it anywhere. I hung the tuning fork by a thread and hit it with a knife and listened to the frequencies with my computer I analyzed the tuning fork in the free-free conditions. In free-free condition, the part has many vibration modes and is not damped by being held or fixed at any location. For us, dangling under gravity is close enough to approximate free-free analysis in Elmer. A free-free part in real life would be floating in space not subject to a gravity. The case we will analyze is called free-free, where the object is not rigidly held at all. (It is also slightly higher because the tension has been increased a little bit). The note is mainly higher because its length is shorter. When you pluck the string again you hear a higher note. When you press the sting onto the neck of the guitar you shorten the length of string that can vibrate. When pluck a guitar string you hear a certain not. How you hold something changes which frequencies can be excited. I’ll examine these factors in depth below. I assume my model is very close to the real life part.īased on my previous work, I’m using 2nd order tetrahedral elements, which gave answers accurate to within 2% of predicted hand calculations in my previous post, Calculating the Vibration Frequency of a Cantilevered Beam.ģ-5) Boundary Conditions, Mesh Density, ad Material Properties My model used average measured dimensions. 1 mm, thicknesses in the forks of the prong only varied by +/. I measured my tuning fork with some vernier calipers, accurate to 0. Material Properties – Is your material correct?.Mesh density – Is the mesh fine enough to give you an accurate answer?.Boundary Conditions – Is the way you’re holding the part in the model the same as the way you’re holding it in real life?.Element types – Did you use elements which will give you an accurate answer?.Geometry – Is your CAD model accurate vs the real part?.When you’re making a model of a part a number of inputs impact your answer. Hardware: Ruler + Vernier Calipers (to measure the tuning fork).Hardware: Microphone/headset microphone (allows you to record audio when you hit tuning fork in real life, I could also have used a cell phone).Software: Audacity (audio analysis/recording, analyzes the frequencies in an audio file).Software: Libreoffice/Excel (spreadsheet, conversion of FEA eignevalues into frequencies).Compare the calculated to actual results.Ping test the part in real life to find the actual frequencies.Import mesh into Elmer (Finite Element Analysis (FEA) software), solve for frequencies in Elmer.So I bought a tuning fork off and compared the Elmer analytical frequencies to the real life free-free frequencies. I’ve shown that Elmer accurately calculates a cantilevered beam’s lowest natural frequency, but I wanted to test Elmer on a real part. ![]()

Nothing is stopping you. Each relic is class agnostic, so you can mix and match them to create interesting combinations. You can have one Relic equipped at a time, which opens up an entirely new skill tree that includes an “ultimate” ability with a very long cooldown, similar to those you might see in a MOBA. A mage with vampiric berserker abilities? Nothing is stopping you.It gets a little more exciting with the introduction of Relics, which ended up being my favorite part of the progression system. But each only features a handful of abilities to invest in right now, and since they’re gated at five level intervals, the choices you have upon levelling up are usually pretty limited.Ī sniper with lightning powers? Sure. Each has two main skill trees with a different focus – the Sharpshooter has one focusing on direct ranged damage and one focusing on summonable creatures, while the Railmaster has one focused on melee combat and one focused on making his train bigger and nastier. ![]() ![]() The options for customizing these classes are a little bit lackluster, too, especially compared to some other recent ARPGs. There is an unlockable reload skill that refills your ammo instantly, and while it suits the fantasy the sharpshooter is trying to represent, it was far too rare that it let me feel like I was making interesting resource management decisions. That sounds great, but their ammo resource gauge is basically just a fancy stamina bar that recharges quickly when not in use. The Sharpshooter, for instance, is a savvy hunter who can summon various companions and has a whole toolbelt of powerful ranged attacks. The hilariously over-the-top Railmaster reimagines the concept of a pet class by summoning a battle train that follows you around on rails you leave behind as you move, to which more cars with different uses can be added by investing in the skill tree.Įach of the four playable classes has a very distinct and flavorful aesthetic and identity.Not all of them are quite as fun in practice as they seem in concept, though.

It’s got a certain charm to it, but it’s all so painfully familiar, like your slacker roommate’s first attempt at running a Dungeons & Dragons campaign.Īt least things get a little more interesting when it comes to the class design. You’ve got goofy goblins that lean on the comedy crutches of over-the-top voice acting and Saturday morning cartoon hijinks. Every NPC seems to be defined by a single personality archetype. It’s not like previous Torchlight games were heavy on story either, but Torchlight 3 doesn’t even seem to be trying. Something about an ancient evil reawakening, blah blah blah. Torchlight 3 doesn’t put its best foot forward as it tries to introduce us to a story premise that isn’t really trying to be anything more than ultra generic fantasy. When I could be playing Diablo 3 or Wolcen (now that it's been patched a bit) or Path of Exile or even one of the older Torchlight games, I keep looking for a reason why I’d choose Torchlight 3… and so far, the early access version hasn’t really given me one. The problem is that it doesn’t really do much to effectively set itself above or apart from the embarrassment of riches we have to pick from in this genre right now. It’s a flashy, bombastic, nicely-paced action-RPG with tons of enemies to slash, blast, and explode for the tasty loot inside. There’s nothing desperately wrong with Torchlight 3, which just came out in Early Access form a week ago. ![]() ![]() Various airfoils serve different flight regimes. The thicker boundary layer also causes a large increase in pressure drag, so that the overall drag increases sharply near and past the stall point.Īirfoil design is a major facet of aerodynamics. The thickened boundary layer's displacement thickness changes the airfoil's effective shape, in particular it reduces its effective camber, which modifies the overall flow field so as to reduce the circulation and the lift. The drop in lift can be explained by the action of the upper-surface boundary layer, which separates and greatly thickens over the upper surface at and past the stall angle. At about 18 degrees this airfoil stalls, and lift falls off quickly beyond that. With increased angle of attack, lift increases in a roughly linear relation, called the slope of the lift curve. The curve represents an airfoil with a positive camber so some lift is produced at zero angle of attack. ![]() Airfoils are used in the design of aircraft, propellers, rotor blades, wind turbines and other applications of aeronautical engineering.Ī lift and drag curve obtained in wind tunnel testing is shown on the right. Airfoils are highly-efficient lifting shapes, able to generate more lift than similarly sized flat plates of the same area, and able to generate lift with significantly less drag. This does not mean the object qualifies as an airfoil. When the wind is obstructed by an object such as a flat plate, a building, or the deck of a bridge, the object will experience drag and also an aerodynamic force perpendicular to the wind. An airfoil-shaped wing can create downforce on an automobile or other motor vehicle, improving traction. Swimming and flying creatures and even many plants and sessile organisms employ airfoils/hydrofoils: common examples being bird wings, the bodies of fish, and the shape of sand dollars. Sails are also airfoils, and the underwater surfaces of sailboats, such as the centerboard, rudder, and keel, are similar in cross-section and operate on the same principles as airfoils. Airfoils are also found in propellers, fans, compressors and turbines. ![]() The wings and stabilizers of fixed-wing aircraft, as well as helicopter rotor blades, are built with airfoil-shaped cross sections. Overview Streamlines around a NACA 0012 airfoil at moderate angle of attack Lift and drag curves for a typical airfoil inviscid potential flow) the lift force can be related directly to the average top/bottom velocity difference without computing the pressure by using the concept of circulation and the Kutta–Joukowski theorem. This pressure difference is accompanied by a velocity difference, via Bernoulli's principle, so the resulting flowfield about the airfoil has a higher average velocity on the upper surface than on the lower surface. The air deflected by an airfoil causes it to generate a lower-pressure "shadow" above and behind itself. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. Most foil shapes require a positive angle of attack to generate lift, but cambered airfoils can generate lift at zero angle of attack. The lift on an airfoil is primarily the result of its angle of attack. This force is known as aerodynamic force and can be resolved into two components: lift ( perpendicular to the remote freestream velocity) and drag ( parallel to the freestream velocity). ![]() When oriented at a suitable angle, a solid body moving through a fluid deflects the oncoming fluid (for fixed-wing aircraft, a downward force), resulting in a force on the airfoil in the direction opposite to the deflection. Foils of similar function designed with water as the working fluid are called hydrofoils. Wings, sails and propeller blades are examples of airfoils. Streamlines on an airfoil visualised with a smoke wind tunnelĪn airfoil ( American English) or aerofoil ( British English) is a streamlined body that is capable of generating significantly more lift than drag. The dolphin flipper at bottom left obeys the same principles in a different fluid medium it is an example of a hydrofoil.

This formula will show what is the surface area of the triangular prism. \(\frac\times 8 \times 3+(5+5)\times 6\) The surface area of a triangular prism is nothing but the amount of space on the outside. The surface area of Prism 2 × Area of the base + Perimeter of the base × Height. Because in a prism, the roof and the floor have the same shape and their surface areas are always the same which can be found out by. Since the kaleidoscope is in the shape of a triangular prism, we can use the formula for the surface area to find its height.ĥ76 = 9 \(\times\) 7.8 + (9 + 9 + 9)H ĥ76 – 70.2 = (27)H The surface area of a prism is always equal to the sum of the areas of all its faces, which includes the floor, walls, and roof. The total surface area is the sum of these. The lateral faces (or sides) are rectangles. A right prism is composed of a set of flat surfaces. So we can calculate the surface area of the prism using the surface area of a parallelepiped formula as, Surface area of prism 2lw + 2lh + 2wh. This shape has a square base with 4 4 triangular sides. A triangular prism has 2 2 triangular faces on the ends that are connected by three rectangles faces. ![]() Look for the characteristics of a triangular prism. Solution: The prism is in the shape of rectangular parallelopiped. Look at the shape below and determine if it is a triangular prism or not.

We can find the surface area of the triangular prism by applying the formula, The height of the triangular prism is H = 15 cm The base and height of the triangular faces are b = 6 cm and h = 4 cm. Find the surface area of the triangular prism with the measurements seen in the image.įrom the image, we can observe that the side lengths of the triangle are a = 5 cm, b = 6 cm and c = 5 cm. ![]() ![]() I think they probably need to comb over their feedback from the EA in a more thorough way. If that's too OP then maybe just make it really hard to find a longbow in this game? I mean right? I don't know, seems like something they could have figured out by now, cause this issue has definitely been raised. The distant spell meta magic range basically. In BG1 the longbow had a range of 100 ft (thanks Canada! hehe) so right around twice the distance 18m distance we get in BG3. If Lae'zel was a character we met in the second act, with those sorts of powerups, but instead we kind of build around her baseline right? Again, I wouldn't trade Lae'zel for a longbow here, but still you can sorta see why we ended up where we did on that one. Not that I'd take anything away from Lae'zel, since she's a top fav, but if our first brawler was a somewhat more regular fighter who couldn't jump quite so far, there'd be more reason to have a fighter who uses a bow. These allow her to operate at a range, but with a Greatsword hehe. They certainly managed to still make Githyanki crossbows annoying as hell when the bolts are being aimed at the party by enemies, but mostly that's coming from stuff like poisons or the reduce potion hehe.Īnother issue is that the literal first character we meet in this game is a Gith fighter who has all these crazy astral jump and teleportation maneuvers. They could probably have addressed some of these issues by just having fewer enemies with longbows and ranged weapons or something similar, so it wouldn't always be a battle of edge pans like it probably would otherwise. I know it's working on some level, because there are instances when Lae'zel will sometimes have to break out her ranged weapon, but half the time that's from a pathing issue or a body block from a friendly character or a failed jump that got hung on a doorway or something. ![]() Sure they're probably too overpowered in the tabletop but I think they overcompensated here. When you can cover the same distance jumping in full armor or using misty step, archers become pretty lackluster. When you can throw an axe the same distance as you can shoot an arrow from a bow that's a bit of a problem. Yeah this has been brought up many times going back to early 2020.įrustration with the cursor targeting, sightlines vs environmental obstructions or verticality, the overall range of bows relative to thrown weapons or ranged spells, the arcs of the projectiles etc. Same builds everywhere, because there is no reason to ever pick light crossbow over hand crossbow, etc. Unless you are doing some archery build, the only thing that matters is damage, so hand crossbow wins due to bonus attack actions, while Heavy Crossbow wins due to lack of loading property and having highest damage overall, leaving magic items aside.Īs it is right now, there is scarcely any reason to pick shortbow or any other weapon over the two I wrote about earlier. You can shoot with bonus action, making it strictly superior to other ranged weapons. All ranged weapons are functionally the same, meaning Hand Crossbow reigns supreme. So, this perk is worse that's it's melee equivalent, Great Weapon Master. This translates to roughy 45 meters and 180 meters give-or-take. ![]() Normally a longbow can shoot 150 feet/600 feet with disadvantage. ![]() Sharpshooter does not let you ignore maximum range penalty. As you basically double your hit chance and damage, while Sharpshooter requires -5 attack roll. Tavern Brawler is stricly superior than Sharpshooter when it comes to dealing damage. This causes some serious problems, let's list them shall we: So, no matter which one you use, the only one that matters is the one that gives you the most damage, as the range is identical for some unknown reason. This includes: Longbow, Hand Crossbow, Shortbow, both Crossbows, etc. First of all, for those that do not know, all ranged weapons and thrown weapons have got a maximum range of 18 meters. Who the hell thought it was a good idea to make all throwing weapons and all ranged weapons have the exact same bloody range?īecause let me tell you, it was a horrible idea. ![]() ![]() ![]() ![]() ![]() Enhance your editing process with increased performance and responsiveness, ensuring a seamless experience that aligns with your creative vision. ![]()
