A suddenly applied compressive load induces in a 250 mm long steel bar a maximum stress of 200 MPa. If the bar has a cross-sectional area of 800 mm² for half of its length and a cross- sectional area of 500 mm² for the remaining half, calculate (a) the magnitude of the load; (b) the energy absorbed; and (c) the instantaneous extension of the bar. (Take E as 200 GPa.)
