a) A tie bar of length 2.5 m and diameter d carries a direct uniaxial load of F. The modulus of elasticity of the bar material is 180GPa. Determine the induced tensile stress, the tensile strain and the change in length that occurs.

d mm =4

F kN=4

I b} A block of material shown below has a shear modulus of 50 ITS-Pa. Determine the shear stress and the shear strain induced by the F shearing farce. 150mm
