Review I Constants Learning Goal: To practice Problem-Solving Strategy 8.1 Static equilibrium problems. Correct 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 diceps = 2.50 cm from the elbow, how much force Fices must the biceps exert to hold a 500 g ball at the end af the forearm...
