A uniform cube is subjected to volume compression. If each side is decreased by 1.5%, then the bulk strain is:
Correct answer: A. 0.045
- A. 0.045
- B. 0.03
- C. 0.45
- D. 4.5
Explanation
For small changes, the bulk strain (ΔV/V) is approximatelythree times the linear strain (ΔL/L). Since each sidedecreases by 1.5% (or 0.015), the total bulk strain isapproximately 3 × 0.015 = 0.045.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.

The rubber cord of a catapult has a cross-sectional area of 1 mm² and a total unstretched length of 10 cm. It is stretched to 12 cm and then released to project a stone of mass 5 g. Taking Young's modulus Y of rubber as 5 × 10⁸ N/m², the velocity of projection will be:
A ball falling in a lake of 200 m shows a decrease of 0.1% in its volume. The bulk modulus of elasticity of the material of the ball is: (take g = 10 m/s²)
Two wires are made of the same material and have the same volume. However, wire 1 has a cross-sectional area of A, and wire 2 has a cross-sectional area of 3A. If the length of wire 1 increases by Δx on applying force F, how much force is needed to stretch wire 2 by the same amount?
