What is Young’s modulus of a rigid body?

The young's modulus of a liquid is

A brass wire of length 4.5m with cross-section area of 3xx10^(-5) m^2 and a copper wire of length 5.0 m with cross section area 4xx10^(-5) m^2 are stretched by the same load. The same elongation is produced in both the wires. Find the ratio of Young’s modulus of brass and copper.

Let a steel bar of length 'l', breadth 'b' and depth 'd' be loaded at the centre by a load 'W'. Then the sag of bending of beam is (Y=Young's modulus of material of steel)

What is Young’s modulus? Describe an experiment to find out Young’s modulus of material in the form of a long string wire.

What is a rigid body? What is meant by axis of rotation of a rigid body?

A telephone wire 125m long and 1mm in radius is stretched to a length 125.25m when a force of 800N is applied. What is the value of Young’s modulus for material of wire?

Young's modulus for a wire of length L and area of cross-section A is Y. What will be Young's Modulus for wire of same material, but half its original length and double its area?

In determination of Young's modulus of elasticity of a wire, a force is applied and extension is recorded. Initial length of wire is '1 m'. The curve between extension and stress is depicted, then Young's modulus of wire will be

A stretching wire has a Young's modulus Y and energy density E. The strain in a stretching wire is

The Young's modulus of a material is 2xx10^(11)N//m^(2) and its elastic limit is 1xx10^(8) N//m^(2). For a wire of 1 m length of this material, the maximum elongation achievable is
