'A model for the elbow joint models the bicep muscle connecting to the horizontal forearm by a vertical tendon 4cm from the elbow joint. A mass m is held in the hand 30cm from the elbow joint. If the maximum tension that can be exerted by the tendon before injury occurs is 2250N, find the maximum mass that can be held in this way.' Im stuck on this question
(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

3) To strengthen his arm and chest muscles, a 6-slug athlete who is 6'6" tall is doing push-ups as shown in the figure below. His centre of mass is 3'9" from the bottom of his feet, and the centres of his palms are one foot from the top of his head. Find the force that the floor exerts on each of his feet and on each hand, assuming that both feet exert the same force and both palms do likewise. Begin with a free-body diagram of the athlete. 6'6" K–1'-
