Calculate the net torque about the axle of the wheel shown in the figure. Assume that a friction torque of 0.39 m·N opposes the motion.

2. Relevant equations

3. The attempt at a solution

(0.2m)(20N)(sin135)=2.83

(0.1m)(35N)(sin 135)=2.47

(0.2m)(30N)(sin90)=6

-2.83m·N-2.47m·N+6m·N=0.7m·N

0.7m·N+.39m·N=1.09m·N

Is this how you deal with friction in a torque problem??
