The least count of vernier caliper is the smallest measurement that can be read on the scale.

• The least count is determined by the number of divisions on the vernier scale and the main scale.

• It is usually 0.02 mm or 0.001 inch for a standard vernier caliper.

• The least count can be calculated using the formula: Least count = (1 main scale division) / (number of divisions on the vernier scale).

• For example, if the main scal...read more

Stress vs strain diagram shows the relationship between stress and strain in a material.

• Stress is the force applied per unit area of a material.

• Strain is the deformation or change in shape of a material due to stress.

• The diagram plots stress on the y-axis and strain on the x-axis.

• The slope of the curve represents the material's stiffness or Young's modulus.

• The area under the curve represents the material's toughness.
