A composite bar has a cross-section of three layers of polyester that are 15mm thick each (100mm across) and two layers of Kevlar that are 5mm thick each (100 mm across). The polyester has a modulus of 3000 N/mm^2 and Poisson's ratio of 0.16, and the Kevlar is 140,000 N/mm^2 and 0.28 If the bar is 1 m long and subjected to a compressive axial load of 500 kN, find the change in length, thickness, and stresses.
