[SOLVED] Net torque of uniform disk 1. The problem statement, all variables and given/known data A uniform disk with a mass of 34.8 kg and a radius of 0.32 m is free to rotate about a frictionless axle. Forces of 90.0 N and 125 N are applied to the disk, as the drawing indicates. What is the net torque produced by the two forces? 2. Relevant equations Torque = rFsin(theta) 3. The attempt at a solution I've tried using the equation above...125(0.32)sin90 - 90(0.32)sin90 = 11.2 N*m which is wrong. I know this question is trivial, but I'm pretty frustrated at this point...any help would be great.
