Thank you! I'm sorry it took me so long to reply. I'm having a hard time with the problem. Let's see if I can get this right: After rotating ##\theta##: The new angle between A and the center of the cylinder would be ## \pi/6 + \theta ##. The coordinates of the center of the cylinder at time t...

Thanks for replying, Haruspex. To answer your questions: ##\hat x## is the direction of ##\vec F##, since it is a horizontal force. In 2), the question just mentions writing down the forces involved. ##A## is the force of contact between the step and the cylinder. I do intend to solve for...

Homework Statement [/B] A horizontal force, ##F##, is applied to a cylinder of mass ##M## and radius ##R## (the line of action of ##F## goes through the center) in order for the cylinder to climb over a step of height ##R/2##. 1) Find the torque around ##A## and find force ##F## as a...

It's not a problem from a book, it's just the physical description of of oscillations of gas in a tube solved using Fourier analysis. It is not explained in the books I have, and I couldn't find the step by step analysis online (the usual example is a string) so that's why I asked. Anyway, my...

Help ASAP --- Missing Step --- Gas in a Tube I am dealing with finding normal modes of oscillations in a continuum I have no problems with the string example, but now I have a gas in a tube, one side of the gas has pressure= p_0 and the other side p_0+delta p, they're separated by a wall...

I have the infamous triatomic molecule, with two m masses in the extremes and one 2m mass in the middle, joined by two k springs. I have worked all through the problem (found frequencies, normal modes, drawn configurations, initial conditions) with no hindrances, but I can't seem to get the last...

Here's a good explanation of the historical development of the cross product. HTH Sol.[/color]
