so I meant box 4 not box 1

The difference between boxes 4 and 1 is the change in angular displacement for PE, where it varies with (+) and (-) sign for each answer. I believe that the correct solution should be one containing the element with (phi1-phi2) as we are superimposing one displacement onto the second one. That...

the first box should be checked instead of the 2nd one

1. Small oscilations = vibrations were values of cos/sin(angles) may be approximated to angles [rad]. For cos(phi)=1, sin(phi)/tan(phi)=phi

Also, the only potentially valid equation which I managed to find is as follows:

Truthfully I'm not in possession of any course materials from vibration mechanisms. What I do have are educative videos, lectures provided by my lecturer and notes which I keep track of. I know that sucks but the rest I have to find out on my own which makes me anxious as I'm not sure sometimes...

Hi All, Anyone willing to help out in explaining what eigenfreuqncy for this oscilatory system, would be? Also if anybody knows the equation to calulate this stuff please, if you're willing to share I'd be greatful! Thanks, regards.

Hello everybody. If anyone could help me solve the calculus problem posted below, I would be greatful. Task: Evaluate the moment of inertia with respect to Oz axis of the homogeneous solid A Bounded by area - A: (x^2+y^2+z^2)^2<=zSo far I was able to expand A: [...] so that I receive...

Yes the starting speed (1st initial speed) at the beginning is 0 but we need to find v0, which is the initial speed just before the jump. So that would be problematic. I was trying to reorganize the data the best I could. In terms of the actual wording of the problem the only thing i got was the...

Summary: Mechanics problem related with Calculus (differential equations) Hi everyone, I would like some help in that task, if anyone would be willing to help :) Namely I have a problem from particle dynamics. "D:" means given info... so, D: m,g,h,b, miu. We're looking for v0 and S as given...
