When you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm is 1.50 kg. If the biceps is connected to the forearm a distance d_biceps = 3.50 cm from the elbow, how much force F_biceps must the biceps exert to hold a 900 g ball at the end of the forearm at distance d_ball = 34.0 cm from the elbow. What is the horizontal distance d_forearm between the elbow and the point where the weight of the forearm acts?
