Assertion and are correct

Answer 2

Answer:

When a spring is stretched, the wires that make up the spring are pulled apart.

Explanation:

From the above question,

They have given :

Assertion: The strain produced in a stretched spring is shearing.

Reason: When spring is stretched, the length of wire of spring increases ​

Shearing strain occurs when a force is applied parallel to the surface of an object. When the spring is stretched, the force applied is parallel to the surface of the spring. This force causes the length of the wire to increase, but the cross-sectional area remains the same. This results in a shearing strain being produced in the spring, as the force is applied in the same direction as the surface of the spring.

When a spring is stretched, the wires that make up the spring are pulled apart.

This causes the length of the wire to increase, but the area of the cross-section remains the same. This increase in length creates a shearing force on the wire, which in turn produces a shearing strain on the wire.

This strain is what is known as a shearing strain. Shearing strain is the result of two opposite forces acting on the same object in different directions, which cause the object to deform or change shape. In the case of a spring, this shearing strain causes the wire to become longer and thinner.
