A and B are two steel wires and the radius of A is twice that of B, if they are stretched by the same load, then the stress on B is ...........

If longitudinal strain for a wire is $$0.03$$ and its poisson ratio is $$0.5$$, then its lateral strain is

When the tension in a metal wire is $$ T_1$$ its length is $$ l_1 , $$ when the tension is $$ T_2$$ its length is $$ l_2. $$ The natural length of wire is :

The bulk modulus of an ideal gas at constant temperature is :

The area of cross-section of a steel wire $$\left( Y=2.0\times { 10 }^{ 11 }{ N }/{ { m }^{ 2 } } \right)$$ is $$0.1 { cm }^{ 2 }$$. The force required to double its length will be :

Two wires of same material and same diameter have lengths in the ratio 2 : 5. They are stretched by the same force. The ratio of work done in stretching them is :

A liquid of bulk modulus $$k$$ is compressed by applying an external pressure such that its density increases by $$0.01$$%. The pressure applied on the liquid is:

One end of a slack wire (Youngs modulus $$Y$$, length $$L$$ and cross -sectional area A) is clamped to a rigid wall and the other end to a block (mass m) which rests on a smooth horizontal plane. The block is set in motion with a speed v. What is the maximum distance the block will travel after the wire becomes taut?

The relation between Young's modulus $$Y$$, bulk modulus $$K$$ and modulus of elasticity $$\sigma$$ is

A metallic rod of length $$l$$ and cross sectional area $$A$$ is made of a material of Young's modulus $$Y$$. If the rod is elongated by an amount $$y$$, then the work done is proportional to
