    A cylindrical rod of 380mm long and 10mm in diameter is subjected to a tensile load
    of 25kN. If the rod is to allow neither plastic deformation nor an elongation of more than
    0.9 mm, select a suitable material for the rod from the table below. Justify your choice(s) with full calculations and explanations.


    Material Young’s modulus(GNm-2) Yield Strength(MNm-2) Tensile strength(MNm-2)




    Aluminium..............70.......................................255..............................420
    Brass alloy............100......................................345...............................420
    Copper.................115......................................250...............................290
    Steel alloy.............207......................................450...............................550
