JSW Steel CNC Machine Operator Interview Questions and Answers

Torque is a measure of the twisting force applied to an object.

• Torque is the product of force and the distance from the axis of rotation.

• It is a vector quantity, meaning it has both magnitude and direction.

• Torque is commonly used in mechanical systems to measure rotational force.

• For example, when tightening a bolt with a wrench, the torque applied determines how tight the bolt becomes.

• Torque is measured in units of for...read more

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

• Stress is the external force or load applied to a material.

• Strain is the measure of deformation or change in shape that occurs in response to stress.

• Stress and strain are related through the material's elastic properties.

• Stress is typically measured in units of force per unit area (such as pounds per square inch or p...read more

Young's modulus is a measure of the stiffness of a material.

• Young's modulus is the ratio of stress to strain in a material under tension or compression.

• It is a measure of how much a material will stretch or compress under a given amount of force.

• Materials with a high Young's modulus are stiffer and less elastic than those with a low Young's modulus.

• For example, steel has a high Young's modulus, while rubber has a low Y
