The discussion focuses on calculating the normal force exerted by each hand and foot of a person performing pushups, given a total weight of 584 N and specific distances from the center of gravity. The center of gravity is located at the waist, with distances of 0.410 m from the waist to the hands and 0.840 m from the waist to the feet. The solution involves analyzing torques around the fulcrum, which is the waist, and applying the principles of static equilibrium to determine the forces acting on the hands and feet.
PREREQUISITESStudents in physics, particularly those studying mechanics, as well as fitness professionals and physical therapists interested in understanding body mechanics during exercises like pushups.
This is a torque problem. Analyse the torques about the fulcrum. Where is the fulcrum? What kind of a lever is this? Find the normal force at the top (or bottom) of a push- up - ie. ignore any angular acceleration. Also, assume there are no differences between left and right hands and between left and right feet.Pinkchika88 said:Homework Statement
