I think you're right, did it a few hours ago...felt ashamed to even hand it up...haha thanks anyway to you and all who helped!

I wasn't asking you, I was asking the other people viewing. And if you read my reply, you'd see that I was already doing what your "advice" specified.

Haha trust me, I'm hitting the books constantly all day and night, my only break is to ask on here, because I'm getting nowhere. Seriously, any tips or last minute advice?

Something like "Always start with..." or "Definitely know...(eqn)" ...annnnyone??

Anyone else have any tips? Ways to get some marks?

Thanks very much! Based on your experience, would you say it would be even possible to learn what you said and pass the exam, with say, 10 hours of study? Assuming I have no knowledge in the subject (even though I do, but if I didn't). I only ask because I have more exams following and am...

That's exactly it! I'm starting to realize this, and realize I may not be able to pass the exam at this point without proper understanding of the fundamentals. But yes, at this point I am just learning recipes to solve the problems and how to tweak that recipe for different problems, and I...

Hi, I've been studying fluid mechanics for my mech. engineering degree for the past few months. Unlike my other subjects (mechanical analysis, thermodynamics, automated systems, mechanical vibrations), I can't seem to grasp the problem-solving technique. The annoying thing is, I find the...

Oh, is it for Φ=-0.9, because cos(0) is the maximum value you can get?

Thank you! So it the angular displacement, θ = Acos(ωt + Φ) = 0.037cos(0 + 0.9)?

Would it be sin(θ-0.9), so ψ = 0.9? On a different topic, I'm able to do most of the questions now, but I have just 2 last queries for you; 1. In Question 6(a) I derived the formula fine, but what are the units for ωn in terms of E,I,L and m? I did it as ωn = √(Gpa*mm4)/(mm3*kg) =...

Ah they cancel, that's cool! But does that only work for this particular example? With the θ' coefficient being = 0? Basically, I'm asking if that's a way to calculate ω in every question, not just this one? Because most past exam questions ask for ωn, so if I find the equation of motion, then...

Is the coefficient of the θ variable always = ω2? If so, can't I just get ω2 = √27.513 (the coefficient in front of θ) = 5.245? Is that the natural frequency value? How do I go about reading the amplitude and φ from the graph anyway? A seems to be about 3.9 (?) but how do I read φ ? The sin...

Okay, so that gives me the correct DE, now is finding the roots of the characteristic equation the next step? (with b=0)

Ah yes, the table, that makes sense! So it would be θ''In = (+m2gl2 - kl3 )θ...right?
