2) A solid block of dimensions a=400 mm, b=75 mm and c=50 mm is made of an isotropic elastic material with a Poisson's ratio of 0.27. Three forces act axially as shown and have magnitudes Px=120 KN; Py=-100 kN and P = -60 kN. Find the deformation in all 3 directions. If instead of three forces acting, only a force in the x direction is acting, determine the magnitude of that force such that the deformation in the x direction in the two cases are identical. Set E=60 GPa 3) Determine the change of volume caused in the block due to the application of the forces (Bulk Modulus Problem). Set E=60 GPa, poisson Ratio v=0.25, assume isotropic material c=60 mm T 100 kN b = = 50 mm 50 kN a = 100 mm 180KN
