A laminae is considered a plate with only biaxial stresses in plane stress conditions. From Generalized Hooke’sLaw that you learnt in Strength of Materials, we know these equations to be true in such conditions. Or in other words, we know the Compliance matrix that represents the laminae. Find the Stiffness matrix of thesame laminae. Or in other words, prove that the equations below are true for the same laminae. The equationsbelow are what we discussed in Lecture. Assume the laminae has isotropic properties.

A high-impulse universal testing machine is being used to determine the Young's Modulus of a rectangular solid specimen (l = 20 cm, t = 1.5 cm, w = 2 cm). The machine produces 35,000 Ns that causes the impact force of compression resulted to a 1 mm deformation in the length of the specimen in 0.05 s. Determine the Young's modulus of the specimen expressed in MPa. Round off your answer to the nearest whole number
