VE Commercial Vehicles Diploma Trainee Engineer Interview Questions and Answers

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

• Stress is a measure of the internal forces within a material, typically caused by external loads.

• Strain is the measure of how much a material deforms or changes shape in response to stress.

• Stress is usually expressed in units of force per unit area (such as N/m^2 or Pa), while strain is dimensionless.

• Stress can be te...read more
