QUESTION 5) Two elastic bodies made of different materials are placed in a rigid cavity and their surfaces are in full contact. In the vertical direction, a uniform pressure force acts on body 1 with 120MPA and on body 2 with 40MPA. Calculate all the stresses in objects 1 and 2 and the length changes in the z-axis direction.
