Q4 Direct stresses of 160N/mm2 tensile and 120 N/mm2 compressive exist on two perpendicular planes at a certain point in a body. They are also accompanied by shear stresses on the planes. The greatest principal stress at the point due to these is 200 N/mm2. What must be the magnitude of the shearing stresses on the two planes? What will be the maximum shearing stress at the point?

A rectangular steel block is 3 inches long in the x direction, 2 inches long in the y direction, and 4 inches long in the z direction. The block is subjected to a triaxial loading of three uniformly distributed forces as follows: 48 kips tension in the x direction, 60 kips compression in the y direction, and 54 kips tension in the z direction. If the Poisson’ Ration is 0.30 and the modulus of elasticity is 29xksi, determine the deformations at each direction. Also, determine the single uniformly distributed load in the x direction that would produce the same deformation in the y direction as the original loading.
