A metal block is experencing an atmospheric pressure of 10⁵ N/m². When the same block is placed in a vaccum chamber, the fractional change in its volume : (the bulk modulus of metal is 1.25 x 10¹¹ N/m²)

The upper end of a wire, 1 m long and 4 mm radius, is clamped. The lower end is twisted by an angle of 30^o. The angle of shear at the surface is :

The volume of a solid rubber ball when it is carried from the surface to the bottom of a 200 m deep lake decreases by 0.1%. The value for bulk modulus of elasticity for rubber will be :

A thick rope of density 'ρ' and length 'L' is hung from a rigid support. The Young's modulus of the material of rope is 'Y'. The increase in length of the rope due to its own weight is :

The length of an iron wire is L and area of cross-section is A. The increase in length is l on applying the force F on its two ends. Which of the statement is correct ?

The magnitude of the force developed by raising the temperature from 0^oC to 100^oC of the iron bar 1.00 m long and 1 cm² cross-section when it is held so that it is not permitted to expand or bend is :

(Given : α = 10^-5 /^oC and Y = 10¹¹ N/m²)

The Poisson's ratio for a material is 0.1. If the longitudinal strain of a rod of this material is 1 x 10^-3, then the percentage change in the volume of rod will be :

A uniform elastic plank moves due to a constant force F placed over a smooth surface. The area of end face is S and Young's modulus of the material is E. What is the average strain produced in the direction of the force?

A 5 m long steel wire is suspended from the ceiling of a room. A sphere of mass 25 kg and 10 cm radius is attached to another end of the wire. The  height of the ceiling is 5.21 m. When the sphere is made to oscillate as a pendulum, then its lowest point just touches the floor. The velocity of the sphere at the lowest point will be : 

(Given : Y = 2 x 10¹¹N/m², radius of wire = 0.05 cm)
