ACC 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

There are various types of gearboxes such as manual, automatic, CVT, DCT, etc. Conveyors can use gearboxes for power transmission.

• Types of gearboxes include manual, automatic, CVT, DCT, etc.

• Gearboxes are used for power transmission in conveyors.

• Conveyor gearboxes can be worm gearboxes, helical gearboxes, etc.

Conveyors are mechanical devices used to transport materials from one location to another.

• Conveyors are used in various industries such as manufacturing, mining, and agriculture.

• They can be powered by electricity, gravity, or manually.

• Types of conveyors include belt, roller, screw, and chain conveyors.

• Conveyors can be customized to fit specific needs, such as incline or decline angles and speed.

• They are designed to inc...read more

Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature.

• Bearings can be of various types such as ball bearings, roller bearings, sleeve bearings, etc.

• Fans can be of different types such as axial fans, centrifugal fans, etc.

• Thermal expansion can cause changes in the dimensions of the bearing and fan components, which can affect their performance and lifespa...read more
