Question

Hi I am in phyiscs I, they have the problem an athlete at the gym holds a 2.5 kg steel ball in his hand. His arm is 70 cm long and has a mass of 4.0 kg .

The magnitude of the torque about his shoulder if he holds his arm straight out to his side, parallel to the floor is τ= 31 N⋅m.

But, I can't seem to find what is the magnitude of the torque about his shoulder if he holds his arm straight, but 30 ∘ below horizontal?

Please include clear details. Thank you!
