The diameter (d) of a solid rod (i.e., with a circular cross-section) is 16 mm and is made from a homogeneous material. The length (L) of the rod is 1.75 m and Young’s Modulus for the material (E) is 250 GPa. When the rod is placed under tension it experiences deformation and a stress (?) of 650 MPa. Calculate the following:

The diameter (d) of a solid rod (i.e., with a circular cross-section) is 16 mm and is
made from a homogeneous material. The length (L) of the rod is 1.75 m and
Young’s Modulus for the material (E) is 250 GPa. When the rod is placed under
tension it experiences deformation and a stress (?) of 650 MPa. Calculate the
following:
(i) Strain energy (U) to 2 decimal places in Joules.
(ii) Strain energy per unit volume (U/V) in J/m3
.
(iii) The change in length ∆L to 2 decimal places in mm.
(iv) The strain (?) due to deformation to 2 significant figures
