India Cements Mechanical Engineer Interview Questions and Answers

Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.

• Thermodynamics studies the transfer of energy in the form of heat and work.

• It involves concepts like entropy, temperature, and energy conversion.

• Examples include the efficiency of engines, refrigeration systems, and phase transitions in materials.

The third law of motion states that for every action, there is an equal and opposite reaction.

• States that when one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object

• The forces always occur in pairs

• Examples include a rocket pushing against the ground to lift off, or a person pushing against a wall

Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings: use balls to reduce friction between two surfaces

• Roller bearings: use cylindrical rollers to reduce friction

• Plain bearings: have a simple surface with no moving parts

• Fluid bearings: use a thin layer of liquid or gas to reduce friction
