Tata Technologies Senior Engineer Interview Questions, Process, and Tips

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.

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

• Strain is the measure of deformation or change in shape of a material.

• Stress and strain are related by the material's modulus of elasticity.

• Example: When a rubber band is stretched (strain), the force applied to it is the stress.

Ductile materials exhibit large deformation before failure, while brittle materials fail suddenly with little deformation.

• Ductile materials have a gradual slope on the stress-strain curve, showing plastic deformation before fracture.

• Brittle materials have a steep slope on the stress-strain curve, showing little to no plastic deformation before fracture.

• Examples of ductile materials include steel and aluminum, while exa...read more

Stress is the internal force per unit area within a material, while pressure is the external force per unit area exerted on a surface.

• Stress is a measure of the internal forces within a material, while pressure is a measure of the external forces acting on a surface.

• Stress is a scalar quantity, while pressure is a vector quantity.

• Stress is measured in units of force per unit area, while pressure is measured in units of...read more
