2. The clamp shown is made of ASTM 20 cast iron, which has a maximum tensile strength of 152 MPa and a maximum compressive strength of 570 MPa. If a factor of safety of 3 is required, determine; a) The largest clamping force P which may be applied based on the stresses generated at points A and B in section a-a. b) Using the force determined from part (a), determine the location of the neutral axis. 32 mm a 2 mm radius 20 mm 4 mm Section a-a
