Please show complete solution with formula and free body diagramA rectangular steel block is 4 inches long in the x direction, 3 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 ν = 0.30 and E = 29 × 106 psi, determine the single uniformly distributed load in the x direction that would produce the same deformation in the y direction as the original loading.
For the antenna tower shown, it is supported in its upright position by four high tensile wires. Given specifications of the tensile wire: E = 200 GPa, diameter = 12 mm. If a = 6 m and b = 8 m How far(horizontally in mm) would the tip of the tower move from its original position if P = 8 kN.
A load of P = 93 kN is supported by a structure consisting of rigid bar ABC, two identical solid bronze (E = 103 GPa) rods, and a solid steel (E = 238 GPa) rod, as shown. The bronze rods (1) each have a diameter of 15 mm and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 28 mm. All bars are unstressed before the load P is applied; however, there is a 2.3-mm clearance in the bolted connection at B. Assume L1 = 2.9 m and L2 = 1.3 m. Determine the downward deflection ν of rigid bar ABC. Express your answer in mm rounded to the nearest hundredths.
In the figure shown, the cutaway view shows a solid aluminum alloy of L= 600mm, A= 707mm^2 and E= 70GPa rod within a closed-end bronze of L= 610mm, A= 1206mm^2 and E= 100GPa tube. Before the load P is applied, there is a clearance of 2mm between the rod flange at B and the tube closure at A. After load P is applied, the solid aluminum alloy rod stretches enough so that flange B contacts the closed end of the tube at A. If the load applied to the lower end of the aluminum rod is P= 345KN, calculate:A. The normal stress in bronze tube, in MPa.B. The elongation of bronze tube, in mm.
