This video should really be renamed "Ranking MECHANICAL Engineering Courses from Easiest to Hardest", because calc 2 and 3 are exceptionally useful in high level engineering fields like Electrical engineering, where monitoring electromagnetic waves requires an enormous amount of calculus skill. Also its useful in structural engineering as you can model say how fast a room fills with gas. Chem 1 while it may be trivial, is the start for any chemical engineer. Calculus 2 is powerful for computer programmers as the Taylor and Maclauren series are how computers calculate certain values, or programming a physics engine for a video game.

Really depends on the major I guess, I'm doing engineering physics. And we use calc 3 like crazy for electromagnetic field theory and even for things like analytical mechanics. Calc 2 and beyond is required when we're dealing with upper maths courses like linear analysis or when doing signal analysis, integration is just a big part of doing transforms. We also integrate alot in our quantum mechanics course. I like the facts that we keep using the stuff we're learning.

This guy undervalues linear algebra and calc 3 which are pretty essential for higher level understanding of upper div eng courses. If you have any expectation of going into grad school, matlab is unavoidable. Also you learn integration methods in calc 2 which without it differential equations is pretty rough

Hmm I think every uni is different and idk if they would relate to my experience, but my take is: There are 2 MAIN branches, if you want to work on mechanical engineering as an actual engineer or you see yourself more as an investigator/scientist. If (and only if) you would like to do investigation take math and more "theoretic" classes. In my experience, you need math to understand what you are doing but it should not be your priority. The more "applied" a course sounds, the more useful it will be if you want to actually work on design or work with machines and installations in general. Programming is useful, 3d design, technical drawing, excel, and in general any course that does not HEAVILY rely on full theoretic base (all courses should rely on theory, and you -should- understand it with importance, but it should not be the final objective). Now, idk if "pre" mechanical engeneering will include some of this more applied stuff. First and second year usually are mostly theory. Let me know if you need anything

Good video but I got to disagree with many of them. As an example Calc III is heavily used in elasticity theory, FEM and FEA, some fluid mechanics and dynamics as well as CFD... It's pretty much the gateway to solving any 3D problem in engineering, and 3D is what real life is like. Sure simplifications to 2D are most of the time possible but with less accuracy and a much lower tolerance in structures etc ...

Maybe your electrical subjects is lite enough, that's why it's easy to you. But electrical especially electronics is the most hardest to understand and difficult to solve like a very complicated electronics circuits because every component has tons of parameters and characteristics curve.

In Mechanical Engineering at UOttawa, Math for Engineers (ME 303 in your video) is equally useless. It's basically an entire course dedicated to Fourier transform, with an overload of theoretical math that never gets used again. And at the end of the course, all that we learned could only be applied to extremely simple geometries, so basically circles, squares, rectangles, and spheres.

@saintsword23

2 жыл бұрын

Initial speed is something you'd have to calculate yourself, since point P is a point in space orbiting the Earth. The wording is poor (it's not "taking off" from that point, it's beginning a maneuver). You don't need to know the mass of the shuttle because the question isn't asking about the amount of force it'll take, only the change in speed. Part a) is easy and a first year student could solve it. Part b) is probably the bulk of the problem and what you learned in the Dynamics course. I'm not sure, I was a CS student and only took Mechanics (thus why I know part (a) is solvable by a first year student). This might require a differential equation since the shuttle will lose speed while traversing between the two points. Part c) I don't understand. Since the satellite is 300,000km up and point P is 200,000km up, the satellite and the shuttle will have different orbital periods and it's more just a matter of timing. If they're meant to be on the same orbit but just opposite of each other as the diagram shows, and one of the numbers is in error, then the shuttle will never hit the satellite during this maneuver.

@chawkispam6359

2 жыл бұрын

@@saintsword23 aah okay I didn't get that it was orbiting the earth. The last part is pretty straight forward from there. Draw a circle with point P and than just draw a circle around that. At its furthest point, the r (shuttle to earth) is larger than 3Mm. While at the closest point the r is smaller than 3Mm. Therefore there are at least 2 interceptions. But the satellite is at the opposite point of P, so we only have to account for 1 interception. Than just calculate the place where the shuttle intercepts with the satellite trajectory (keep in mind that the satellite will probably make full laps before the shuttle is in reach). From there you can calculate the speed at which the shuttle probably reaches the point at the same time as the shuttle. The question could be better understand as "which shuttle speeds should be avoided"

Calculus over linear algebra? That's a stretch.

Everyone is a little different I guess

Him: “chemistry is pretty useless.” Also how do you think calculus and diffeq aren’t useful? Those are used in upper division courses all the time. Me, a chemical engineering working in a chemistry lab: 👁 👄 👁

This guy's video is baffling lol ...no wonder he's an ME. He literally said Calc 2 is useless in upper year courses and Calc 1 is more useful LMFAO. He is full of shit.

@@USNEM yeah. Calc 1/2 are super useful for upper division classes.

To be honest, chemistry for engineers is roughly the equivalent of a grade 11 chem course. Aside from long lab reports, you just learn rate laws and i.c.e tables with a touch of the "pv = nrt" law. I agree with the video, the course is complete trash.
