• Examples of manufacturing industries include automotive, electronics, pharmaceuticals, and food processing.

The formula for spring constant is the ratio of the force applied to the displacement it causes.

• The formula for spring constant is given by Hooke's Law: F = kx

• F represents the force applied to the spring

• k is the spring constant

• x is the displacement caused by the force

• The unit of spring constant is N/m (newtons per meter)

Stress-strain curve shows the relationship between stress and strain in a material.

• The curve starts at the origin and goes up to the point of yield.

• The point of yield is where the material starts to deform plastically.

• The curve continues to the point of ultimate strength, where the material breaks.

• The slope of the curve is the modulus of elasticity, which shows the material's stiffness.

• The area under the curve represen...read more
