A steel bar 50 mm in diameter and 2 m long is surrounded by a shell of a cast iron 5 mm thick. Compute the load that will compress the combined bar a total of 0.8 mm in the length of 2 m. For steel, E = 200 GPa, and for cast iron, E = 100 GPa.

Please show the formula used and free body diagram A 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.

A steel wire is 10m long supports a tensile load of 2000N. What is the diameter if the stress is 140 MPa & the total elongation is 5mm.E=200 GPa.

A compression member constructed from steel rod (E = 200 GPa, v = 0.25) has outside diameter of 82 mm. What axial force P will cause the outside diameter to increase by 0.0087 mm? Assume that the material behaves linear elastically.
