Two wire of same material having radius in ratio 2 : 1 and lengths in ratio 1: 2. If same force is applied on them, then ratio of their change in leng...

Two wires are made of the same material and have the same volume. The first wire has cross-sectional area $$A$$ and the second wire has cross-sectiona...

A man grows into a giant such that his height increases to 8 times his original height. Assuming that his density remains same, the stress in the leg ...

A spring of force constant $$k$$ is cut into lengths of ratio $$1:3:4$$. They are connected in series and the new force constant is $$\mathrm{k}$$'. T...

A copper and a steel wire of same diameter are connected end to end. A deforming force F$$_1$$ is applied to the wire which causes an elongation of 1 ...

A force F applied on the wire of radius r and length L and change in the length of the wire is $$l$$. If the same force F is applied on the wire of th...

Within the elastic limit, the corresponding stress is known as

A wire is stretched to double of its length. The strain is

The Poisson's ratio of a material is 0.1. If the longitudinal strain of a rod of this material is $$10^{-3}$$, then the percentage change in the volum...

A steel wire of length 4.7 m and cross-sectional area $$3.0\times10^{-5}$$ m$$^2$$ stretches by the same amount as a copper wire of length 3.5 m and c...
