1. The problem statement, all variables and given/known data http://ready2goxtr.googlepages.com/problem1055.jpg A cylinder having a mass of 2.0kg can rotate about its central axis through point O. Forces are applied as show: F1 = 6.0N, F2 = 4.0N, F3 = 2.0 N, and F4 = 5.0N. Also, r = 5.0cm and R = 12 cm. Find the (a) magnitude and (b) direction of the angular acceleration of the cylinder. 2. Relevant equations Tnet = I [tex]\alpha[/tex] T = rFsin(theta) I = 1/2MR^2 3. The attempt at a solution So far I figured i should find the Net torque. So.. T1 = F1R = 6 * .12 = .72 N * m T2 = F1R = 4 * .12 = .48 N * m T3 = F1Rsin(theta) =?? T4 = 0 How would I find T3?
