8 • Strength of Materials NowE = stress strain Let F, L, A, dl be the force, length, area of cross section, and extension or contraction respectively, then E = F.L A.dl EXAMPLE 2.1: A bar of mild steel has an overall length of 2.1 m. The diameter up to 700 mm length is 56 mm, the diameter of the remaining 1.4 m is 35 mm. Calculate the extension of the bar
