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?
