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!
A force is applied to pull a wheel over a step. Determine the minimum force necessary if h = 3.0 cm, r = 6.0 cm and the wheel has a mass of 1.4 kg. Use g = 10 N/kg. Hint: Take torques about the corner of the step. It is easier to use the perpendicular form of the torque formula because most of the given lever arm information is given perpendicular to the axis of rotation. To determine the lever arm of the weight of the wheel I set up a 30,60,90 triangle base on h and the radius.

The angular momentum vector of a precessing gyroscope sweeps out a cone as shown in the figure below. The angular speed of the tip of the angular momentum vector, called its precessional frequency, is given by t/L, where ris the magnitude of the torque on the gyroscope and L is the magnitude of its angular momentum. In the motion called precession of the equinoxes, the Earth's axis of rotation precesses about the perpendicular to its orbital plane with a period of 2.58 x 10 yr. Model the Earth as a uniform sphere and calculate the torque on the Earth that is causing this precession. N m
