A mild steel shaft (modulus of elasticity = 210 GN/m2) has a stepped circular cross-section. Part A has a diameter of 75 mm and a length of 425 mm. Part B has a diameter of 60 mm and has a length of 375 mm. The shaft carries an axial tensile load of 65.0 kN.


(a) The stress in Part A
(b) The stress in Part B
(c) The strain in Part A
(d) The strain in Part B
(e) The total extension of the shaft.
