TVS Sundram Fasteners Trainee Interview Questions and Answers

Q1. What is stress and strain?
Ans. 
Stress is the force applied to a material, while strain is the resulting deformation or change in shape.
• Stress is measured in force per unit area (e.g. N/m^2 or Pascals)

• Strain is a dimensionless quantity representing the amount of deformation

• Stress and strain are related by the material's elastic modulus

• Example: Stretching a rubber band causes stress and strain in the material

Q2. What are the theories of failure?
Ans. 
Theories of failure are principles used to explain why materials fail under certain conditions.
• The Mohr-Coulomb theory states that failure occurs when the maximum shear stress exceeds the shear strength of the material.

• The Maximum Normal Stress theory suggests that failure occurs when the maximum normal stress in a material exceeds its ultimate tensile strength.

• The Maximum Shear Stress theory states that failure occurs...read more

Q1. What is voltage ?
Ans. 
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
• Voltage is the force that pushes electric current through a circuit.

• It is measured in volts (V).

• Higher voltage means more potential energy for electrons to flow.

• Voltage can be DC (direct current) or AC (alternating current).
