We have two beams with the same length, same width and same height (so these beams have identical cross-section and identical geometry) but one of them is made of stainless steel (with modulus of elasticity Es = 200 GPa) and the other one is made of wood (with modulus of elasticity Ew = 11 GPa) as shown below. These beams are rigidly attached to the wall at one end and on the other end, we applied the force P (which is equal for both beams). For this problem, find the beam that has the highest normal stress at each cross section and you should justify your answer mathematically.
