A metallic beam having Young's modulus $$Y$$ is supported at the two ends. It is loaded at the centre. The depression of the centre is proportional to

If rigidity modulus is 2.6 times of youngs modulus then the value of poission's ratio is 

A steel wire of mass 3.16 Kg is stretched to a tensile strain of 1 x$${ 10 }^{ -3 }$$. What is the elastic deformation energy if density p=7.9g/cc and Y=2x$$10^{ 11 }N/m^{ 2 }$$

Which of the following substances has the highest value of the young's modulus?

A telephone wire between the two poles is 50 m long and 1 mm in radius.When it is stretched by a load of 65 kg,its length becomes 50.12 m.Calculate Young's modulus of elasticity.

Two wires of equal length and cross-section area suspended as shown in figure. Their Young's modulus are$$Y_1$$ and $$Y_2$$ respectively. The equivalent Young's modulus will be

A thin ring of radius R is made up of a material of density $$\rho $$ and young's modulus Y. If the ring is rotated about its centre in its own plane with an angular velocity $$\omega $$ then the small increase in radius $$(\Delta R)$$ of the ring  is

The Young's modulus of a wire is numerically equal to the stress which will

What happens when the applied load increases and upto breaking stress in the experiment to determine the Young's modulus of elasticity?

The SI unit of stress is same as the SI unit of
