Jindal Industries Private Limited Junior Production Manager Interview Questions and Answers

Q1. What is Hooks low
Ans. 
Hooks law is a principle in physics that describes the relationship between the force applied to a spring and the resulting extension or compression of the spring.
• Hooks law states that the force needed to extend or compress a spring by a certain distance is proportional to that distance.

• The formula for Hooks law is F = kx, where F is the force applied, k is the spring constant, and x is the displacement of the spring f...read more

Q3. What is yield strength
Ans. 
Yield strength is the amount of stress at which a material begins to deform plastically.
• Yield strength is the stress at which a material changes from elastic deformation to plastic deformation.

• It is an important property for materials used in engineering applications.

• Yield strength is typically determined through tensile testing.

• Example: Steel with a yield strength of 300 MPa means it will deform permanently when subje
