I have few doubts to clear. I would like to know the forces acting when we squeeze a foam ball. Mode of squeeze will be by placing the ball between the palm of the hand and the four fingers. What will be the force acting at the center of the ball when we squeeze? Is the force same through out the ball and only the stress is different at different points inside the ball? If not, how do we find out the force? I would like to know about the forces and stresses acting. Any help would be appreciated.
