To practice Problem-Solving Strategy 8.1 Static equilibrium problems. 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 1.10 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 600 g ball at the end of the forearm at distance dball = 30.0 cm from the elbow, with the forearm parallel to the floor? How much force Felbow must the elbow. Part C What is the horizontal distance dforearm between the elbow and the point where the weight of the forearm acts
