To determine Young's modulus of a material of a given wire of length 𝐿 we use:
Correct answer: C. Searle's Apparatus
- A. Melda's Apparatus
- B. Young's Apparatus
- C. Searle's Apparatus
- D. Cavendish Apparatus
Explanation
•Searle's apparatus is used for the measurement of Young's modulus. It consists of two equal-length wires that are attached to a rigid support.•Melde's Apparatus is a simple way to introduce students to the concept of standing waves. The apparatus consists of a string and an oscillator to generate different frequencies. Melde's experiment is ideal to study the behavior of standing waves. Supplied with accessories like pulley and clamp, scale pan, and cord.•Young's modulus apparatus is used to measure Young's modulus of a bar, not a wire.•By measuring the angle of the rod and knowing the twisting force (torque) of the wire for a given angle, Cavendish was able to determine the force between the pairs of masses, by using the Cavendish apparatus.

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.
