(5) We typically place our arms out for when we are crossing a narrow beam/rope. Is it because: (a) The larger leg muscles are unable to be used so we use the arms for leverage to bring our line of gravity back inside base of support; (b) To make our body area wider so the base of support is wider and line of gravity falls within it; (c) To make our body area wider so center of gravity naturally becomes lower and the body is more stable; (d) To utilize force summation to use larger muscles to bring us back into balance

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 2.4 cm from the elbow, how much force must the biceps exert to hold a 42 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.
