A force is applied to 2 m long metal wire, and it stretches 0.3 mm. Assume the  material is elastic. Determine the strain in the wire.

A tensile member in a machine structure is subjected to a steady load of 4.50kN. It has a length of 750 mm and is made from a steel tube having anoutside diameter of 18 mm and an inside diameter of 12 mm. Compute thetensile stress in the tube and the axial deformation.

A Steel column is 3 m long and 0.4 m diameter. It carries a load of 50 MN.Given that the modulus of elasticity is 200 GPa. Calculate compressive stress.

Calculate the force needed to guillotine a sheet of metal 5 mm thick and 0.8 mwide given that the ultimate shear stress is 50 MPa.
