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 1.20 kg . if the biceps is connected to the forearm a distance dbiceps = 3.50 cm from the elbow, how much force fbiceps must the biceps exert to hold a 700 g ball at the end of the forearm at distance dball = 31.0 cm from the elbow, with the forearm parallel to the floor? what is the horizontal distance dforearm between the elbow and the point where the weight of the forearm acts?
