If material of the shaft is 30C8, stress concentration factor is 1.85, notch sensitivity is 0.95 reliability 99.9% and factor of safety is 1.5, find the diameter of the shaft. The load on a bolt consists of an axial pull of 10 kN together with a transverse shear force of 5 kN. Find the diameter of bolt required according to a.Maximum strain energy theory; and b.Maximum distortion energy theory. Take permissible tensile stress at elastic limit = 100 MPa and poisson’s ratio = 0.3
