15 A rod of length 1 05m having negligible mass is supported at its ends by two wires of steel wire A and aluminium wire B of equal lengths as shown in figure the cross sectional areas of wires A and B are 1 mm and 2mm respectively The young s modulus of steel wire is 200 x 10 pa and that of aluminium wire is 70 x 10 pa You are supposed to find the point along the rod where the mass m be suspended in order to produce equal stresses and equal strains in both steel and aluminium wires STEEL ROD Ti 1 05 cm Jol 700 a translational b rotational c both d none 2 The ratio of tensions of steel to aluminium wires in the case of equal stresses is ALUMINIUM ROD 1 05 x 1 Which of the following equilibrium helps us in finding the solution to the problem in both cases T
