Two wires of the same length and material but different radii `r_(1)` and `r_(2)` are suspended from a rigid support both carry the same load at the lower end. The ratio of the stress devedoped in the second wire to that developed in the first wire is

Two wires of same length and material but of different radii are suspended from a rigid support. Both carry the same load. Will the stress, strain and extension in them be same or different ?

Two wires of same length and material but with radii 0.1 mm and 0.2mm are loaded with the same weight. Then

Two wires of different materials are suspended from a rigid support. They have same length and diameter and carry the sameload at the free ends. Will extension, strain and stress be different?

Two wires of same material and same length have radii r_1 and r_2 respectively. Compare their resistances.

Two wires A and B of same length and of the same material have the respective radii r_(1) and r_(2) . Their one end is fixed with a rigid support, and at other end equal twisting couple is applied. Then the ratio of the angle of twist at the end of A and the angle of twist at the end of B will be
