Four identical rods are stretched by same force. Maximum extension is produced in

A spiral spring is stretched by a force. What type of strain is produced in it?

Two steel wires of the same radius have their lengths in the ratio of 1:2 . If they are stretched by the same force, then the strains produced in the two wires will be in the ratio of

Two steel wires of the same radius have their lengths in the ratio of 1:2 . If they are stretched by the same force, then the strains produced in the two wires will be in the ratio of

Two wires of the same radius material have lengths in the ratio 1:2. If these are stretched by the same force the strain produced in the two cases will be in the ratio

Four uniform wires of the same material are stretched by the same force. The dimensions of wire are as given below. The one which has the minimum elongation has:

Figure 14.26 (a) shows a spring of force constant k clamped rigidly at one end and a mass m attached to its free end. A force F applied at the free end stretches the spring. Figure 14.26 (b) shows the same spring with both ends free and attached to a mass m at either end. Each end of the spring in Fig. 14.26(b) is stretched by the same force F. What is the maximum extension of the spring in the two cases ?
