10+ Operations Trainee Interview Questions and Answers

Mechanisms refer to the different ways in which things work or operate. Here are some examples:

• Levers - a rigid bar that pivots around a fixed point

• Pulleys - a wheel with a grooved rim that turns around an axle

• Gears - rotating wheels with teeth that mesh with other gears to transmit power

• Inclined planes - a flat surface that is angled, making it easier to move objects up or down

• Wedges - a triangular-shaped object that is used to split or lift objects

• Screws - an inclined plane...read more

No, diesel cannot be used in a petrol engine due to differences in ignition and combustion processes.

• Petrol engines use spark plugs to ignite the fuel, while diesel engines rely on compression to ignite the fuel

• Diesel fuel is also denser and has a higher energy content than petrol, which can damage a petrol engine's components

• Using diesel in a petrol engine can cause engine knocking, reduced power output, and potential damage to the engine

• Similarly, using petrol in a diesel e...read more

No, petrol cannot be used in a diesel engine due to differences in their combustion processes.

• Petrol and diesel engines have different fuel injection systems

• Petrol ignites more easily than diesel, which can cause engine damage

• Using petrol in a diesel engine can lead to decreased fuel efficiency and increased emissions

• In some cases, using petrol in a diesel engine can cause the engine to stop running altogether

Otto Cycle is a thermodynamic cycle used in spark-ignition engines.

• It consists of four processes: intake, compression, power, and exhaust.

• During the intake process, the fuel-air mixture is drawn into the cylinder.

• In the compression process, the mixture is compressed to a smaller volume.

• The power process is where the spark plug ignites the mixture, causing it to expand and push the piston down.

• Finally, in the exhaust process, the spent gases are expelled from the cylinder.

• The ...read more

2-stroke engines have a power stroke in every revolution while 4-stroke engines have a power stroke in every other revolution.

• 2-stroke engines are simpler and lighter than 4-stroke engines.

• 2-stroke engines have a higher power-to-weight ratio than 4-stroke engines.

• 4-stroke engines are more fuel-efficient and have lower emissions than 2-stroke engines.

• Examples of 2-stroke engines include chainsaws, dirt bikes, and outboard motors. Examples of 4-stroke engines include cars, truc...read more

Cut the cake in 8 pieces with 3 cuts by cutting the cake horizontally, vertically, and then horizontally again.

• First cut the cake horizontally to create 2 equal halves.

• Then cut the cake vertically to create 4 equal quarters.

• Finally, cut the cake horizontally again to create 8 equal pieces.

A boiler is a closed vessel in which water or other fluid is heated.

• Boilers are used to generate steam for power generation or heating purposes.
