Suppose the mass of a forearm with hand is 1.80 kg. If the biceps is connected to the forearm a distance of 2.50 cm from the elbow, what is the magnitude of the torque exerted by the biceps to hold a 44.5 N (about 10 lbs) ball at the end of the forearm at distance of 35.0 cm from the elbow, with the forearm parallel to the floor, in N-m? 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.
