thanx for replying. Does anyone have an idea how to find time. my teacher gave me a hint in saying use a angular kinemaics equation, the one i wrote along with the problem. more info on how to confidently do part a would be appreciated but thanks for replyin

Re yea so i was kinda pissed he didnt put a pic on the test too. but he said that the cylinders are instantaneously stationary when the mass is removed. The smaller cylinder he said can be considered to be inside the big one. The only reason for the two radii is for the inertia equations for...

the wheel rotating in the direction of the heavier mass. okay umm so my teacher wrote that i have to connect the bodies as well. do i combine the inertias of the two masses I = I(of m1) + I(of m2). originally i had (0.5)(20)(9.8)=45(alpha) but he marked it wrong saying i need to connect the...

o okay so u use the parallel axis theorom plus the inertia of the two masses from Point P or the center of mass of dumbell bar?

Homework Statement A system consists off two small disks of masses m and 2m that are on a plane. The length that connects the two mass is of negligible mass is is 3L long. The rod is free to rotate on a vertical axis P and the mass 2m lies L away from P and the mass m lies 2L away from P...

Homework Statement Two masses, m1 and m2, are connected by light cables to the perimeters of two cylinders of radii, r1 and r2, respectively. The cylinders are rigidly connected to each other but are free to rotate without friction on a common axle. The moment of inertia of the pair of...
