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 $1\mathrm{.}20$ kgkg $.$ If the biceps is connected to the forearm a distance dbicepsdbiceps $=3\mathrm{.}00$ cmcm from the elbow, how much force FbicepsFbiceps must the biceps exert to hold a $850$ gg ball at the end of the forearm at distance dballdball $=37\mathrm{.}0$ cmcm from the elbow, with the forearm parallel to the floor? How much force FelbowFelbow must the elbow exert? What is the magnitude of the force exerted by the biceps FbicepsFbiceps? What is the magnitude of the force exerted by the elbow FelbowFelbow?
