Simple Torque Q :)
1. Homework Statement [/b]
An athlete at the gym holds a 3.64 kg steel ball in his hand. His arm is 65.0 cm long and has a mass of 5.59 kg. What is the magnitude of the torque about his shoulder if he holds his arm straight out to his side, parallel to the floor?
2. Homework Equations [/b]
t= rfsin theta
3. The Attempt at a Solution [/b]
t= (0.65)[9.81 (3.64+5.59)] sin 90
= 58.8N*m
WHAT AM I DOING WRONG? i don't get it :*(
