A rectangular block is 137 mm long in the X direction, 93 mm wide in the Y direction, and 56 mm thick in the Z direction. The block is subjected to a triaxial loading of three uniformly distributed forces as follows: 200 kN tension in the X direction, 186 kN tension in the Y direction, and 228 kN compression in the Z direction. If v = 0.3 and E = 200 GPa, %3D determine the single uniformly distributed load in the X direction that would produce the same deformation in the Z direction as the original loading. Answer must be in kN.

Exercise No. 2: Simple Strain 1. A steel rod having a cross-sectional area of 300 mm2 and a length of 150 m is suspended vertically from one end. It supports a tensile load of 20 kN at the lower end. If the unit mass of steel is 7850 kg/m3 and E = 200 × 103 MN/m2, find the total elongation of the rod. Answer: 8 = 54.33 mm 2. A steel wire 30 ft long, hanging vertically, supports a load of 500 lb. Neglecting the weight of the wire, determine the required diameter if the stress is not to exceed 20 ksi and the total elongation is not to exceed 0.20 in. Assume E = 29 x 106 psi.
