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 dbiceps = 3.50 cm from the elbow, how much force Fbiceps
must the biceps exert to hold a 550 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
exert? (Figure 1)
Qu: What is the magnitude of the force
exerted by the biceps FbicepsFbicepsF_biceps? What is the
magnitude of the force exerted by the
elbow FelbowFelbowF_elbow?
