a) A medium carbon annealed steel rod has a rectangular cross section and must cope with a tension of 3 tonnes. The thickness of the rod is 15mm. Calculate the size of the cross section.
b) Calculate the tensile stress in a rod 40mm in diameter with a load of 200kN.
c) Calculate the diameter of a medium carbon steel pin in double shear subjected to a suddenly applied shearing force of 150000N.
