The forearm is a lever in which the bicep muscles provide an upward force which can raise the arm and carry a load. The diagram below represents the forearm as it holds a load of 60 N. The forearm has a weight of 25 N and the centre of gravity, G of the forearm is marked along with the point, P at which it pivots on the adjoining bone. I. Use the principle of moments to calculate the force, B exerted by the biceps to hold the arm and the load stationary
