Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

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 with hand is 1.60 kg. If the biceps is connected to the forearm a distance of 2.2 cm from the elbow, how much force must the biceps exert to hold a 39 N ball at the end of the forearm at distance of 36.0 cm from the elbow, with the forearm parallel to the floor, in Newtons? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
