7 Two rods A and B of radii in ratio 1 2 and length ratio 2 5 are placed between rigid supports with no scope for expansion The material of both rods is same Now if both the rods are heated to produce the same temperature rise then the ratio of thermal stress developed in A and B is 4 1 1 3 1 4 2 1 2 4 1 8 maximum length of a uniform wire
