A strip of metal is originally 5 m long. It is stretched in 3 steps: first to a length of 6 m, then to 7 m and finally to 8 m. The original cross section area of the metal strip is 40 mm?. Compute the final cross section and find the percentage reduction in area due to the above stretching process. Also calculate the force required for the final stage of stretching, assuming that the true stress true strain relation for the material is given as o = 700 0.48 MPa. 5 (c)
