Question

Detine Hooke's law of elasticity. Describe Searle's method
to determine the Young's modulus of the material of the
wire.​

Answer 1

Explanation:

Where stress is the amount of force applied per unit area (σ = F/A) and strain is extension per unit length (ε = dl/l). Since the force F = mg, we can obtain the Young's modulus of a wire by measuring the change in length (dl) as weights of mass m are applied (assuming g = 9.81 metres per second squared).

Answer 2

Answer:

Young's modulus is a measure of the stiffness of a solid material. It is calculated only for small amounts of elongation or compression which are reversible and do not cause permanent deformation when the external applied force is removed. For this reason, it is also called elastic modulus.
