Your biceps connect your shoulder to your forearm. They are connected offset from your elbow so that when you bend your arm, your biceps apply a torque to rotate your forearm. Estimate the force required by your biceps to do a bicep curl (a type of weightlifting). Remember to include the weight of your arm and the weight itself, each applying their torques at the proper locations. Additional Questions 1. How much more weight could you lift with the same bicep force if your biceps attached at the midpoint of your forearm? At the wrist?
