Vernier caliper is a precision measuring tool used to measure small distances with high accuracy.

• Least count is the smallest measurement that can be read on the caliper scale.

• It is calculated by dividing the smallest division on the main scale by the total number of divisions on the Vernier scale.

• For example, if the smallest division on the main scale is 1 mm and there are 10 divisions on the Vernier scale, the least count would be 0.1 mm.

Stress strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.

• Stress strain curve is a graphical representation of the relationship between stress and strain in a material.

• It typically consists of a linear elastic region, a yield point, a plastic region, and a fracture point.

• The slope of the curve in the elastic region is the material's Young's modulus.

• The yield point indicates the stress at which the material begin...read more
