Write down the relation beween three types of moduli and poissons ration?
3 Types of Elastic Moduli. Young's modulus (E) describes tensile elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. It is often referred to simply as the elastic modulus.

A rope is wound around a hollow cylinder of mass 3 kg and radius 40 cm. What is the angular acceleration of the cylinder if the rope is pulled with a force of 30 N?
Assertion: A rigid body can be elastic.
Reason: If s force is applied on the rigid, its dimensions may change.
