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" 1'-

Consider a method for measuring the mass of a person’s arm in anatomical studies. The subject lies on her back, extends her relaxed arm to the side and two scales are placed below the arm. One is placed under the elbow and the other under the back of her hand. Construct a problem in which you calculate the mass of the arm and find its center of mass based on the scale readings and the distances of the scales from the shoulder joint. You must include a free body diagram of the arm to direct the analysis. Consider changing the position of the scale under the hand to provide more information, if needed. You may wish to consult references to obtain reasonable mass values.
The center of mass of a rigid body always lies inside the body. Is this statement true or false? Why?
To strengthen his arm and chest muscles, a 79-kg athlete 2.0 m tall is doing a series of push-ups as shown in the figure below (Figure 1).

6) The system shown in in equilibrium. A mass of 225 kg hangs from theend of the strut, which is connected by a hinge to the ground and makes anangle of 45 degrees with the ground. The strut has a mass of 45.0 kg. Asupport cable is attached from a wall to the center of the strut and it makesan angle of 70 degrees with the vertical wall. a) Find the tension in the cable holding up the strut, which make anangle of 70 degrees with the wall. b) Find the horizontal and vertical forces exerted on the strut by the hinge.

A 68 kg man is in the prone position while during pushups. His feet and hands are 95 cm and 42 cm away respectively from his center of mass. What is the normal force exerted by on each (a) hand and (b) foot?
'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
