Task 3...need complete and accurate solution as soon as possible

Task 3 part A The next section of the design requires you to calculate the induced direct stress, strain and dimensional change in a tie bar subjected to direct uniaxial loading and the shear stress and strain in a component subjected to shear loading of the stresses. A tie bar of length 2.5 m and diameter 10 mm carries an axial load of 12 kN. The modulus of elasticity of the bar material is 180 GPa. a) Determine the induced tensile stress, b) The tensile strain c) The change in length that occurs. (P3 part) Task 3 part B The block of material shown below has a shear modulus of 50 GPa. a) Determine the shear stress and the shear strain induced by the 2 kN shearing force.
