Consider 2 scenarios of an athlete performing push-ups. The first shows the athleteâ€™s body while the arm is straight and the body makes 20Â° angle with the floor line. And the second scenario shows the athleteâ€™s body while the elbow is bent and the body is parallel to the floor.Draw a free body diagram of the athleteâ€™s body in the two positions from each scenario by idealizing the body as a simple supported beam. Assume that the feet two toes can be modelled as a roller support while the two arms â€œlumped togetherâ€ can be modelled as a simple support. Consider the weight of the legs, torso and head separately. Label the forces and use equilibrium equations to write parametric expressions that would enable you to work out the magnitude of the contact forces between your feet and hands with the ground.
