The radii of two rods of the same length and same material are in the ratio of 1:2. If these rods are twisted by applying the same torsional torque, then find the ratio of the angle of twist produced in the two rods.

Two wires of the same length and same material but radii in the ratio of 1:2 are stretched by unequal forces to produce equal elongation. The ratio of the two forces is

Two wires of the same length and same material but radii in the ratio of 1:2 are stretched by unequal forces to produce equal elongation. The ratio of the two forces is

2 rods made of same material have their radii in the ratio 2:1. Same force was applied on them. Ratio of stress in them is

Heat is flowing through two cylindrical rods of the same material. The diameters of the rods are in the ratio 1 : 2 and their lengths are in the ratio 2 : 1. If the temperature difference between their ends is the same, then the ratio of the amounts of heat conducted through them per unit time will be:

Two rods A and B of the same material and length have radii r_(1) and r_(2) respective. When they are rigidly fixed at one end and twisted by the same torque applied at the other end, the ratio [("the angle of twist at the end of A")/("the angle of twist at the end of B")] equal to

Two rods A and B of the same material and length have radii r_(1) and r_(2) respective. When they are rigidly fixed at one end and twisted by the same torque applied at the other end, the ratio [("the angle of twist at the end of A")/("the angle of twist at the end of B")] equal to

Two rod A and B of the same material and dame length have radii r_(1) and r_(2) respectively. When they are rigidly fixed at one end and twisted by the same couple applied at the other end, find the ratio of the angles of twist at the ends of A and B.
