The Young's modulus of a given rod of uniform length πΏ is given by the relation:
Correct answer: C. FπΏ/ππ2π
- A. πΉπΏ/π΄
- B. πΉπ΄/L
- C. FπΏ/ππ2π
- D. Fπ/ππ2L
Explanation
Young modulus=stress/strain FL/Al where l is the extension

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Youngβs 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.

To determine Young's modulus of a material of a given wire of length πΏ we use:
A diameter 'd' and length 'l' wire hangs vertically from a fixed point. The wire is extended by hanging a mass 'M' on its end. The Young modulus of the wire is 'E'. The acceleration of free fall is 'g'. Which equation is used to determine the extension 'x' of the wire?
