Determine the instantaneous stress and elongation of a 30 mm diameter bar if a mass of 60 kg falls through a height of 60 mm on to a collar which is rigidly attached to the bottom end of the bar as shown in Figure Q2. The bar is 1.2 m long and is suspended vertically. The Modulus of elasticity, E, for the material of bar is 210 GPa. Take g = 10 m/s2.
