A force P of 70 N is applied by  a rider to the front hand brake of a bicycle (P is  the resultant of an evenly distributed pressure). As the hand brake pivots at A, a tension T develops in the 460-mm long brake cable (Ae 1.075 mm2 ) which elongates by d 0.214 mm. Find normal stress s and strain in the brake cable.
