Interview Questions and Answers

First law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted. Second law states that entropy of an isolated system always increases over time.

• First law is also known as law of conservation of energy

• Second law explains why heat flows from hot to cold objects

• Second law also states that no engine can be 100% efficient

• Entropy is a measure of disorder in a system

• Both laws are fundamental to understanding energy and its transformation...read more

Two stroke engines have one power stroke per revolution while four stroke engines have one power stroke every two revolutions.

• Two stroke engines have a simpler design and are lighter than four stroke engines.

• Four stroke engines are more fuel efficient and produce less emissions than two stroke engines.

• Two stroke engines are commonly used in small power tools and motorcycles while four stroke engines are used in cars and larger machinery.

• Two stroke engines require a mixture of...read more

Micrometre is a unit of measurement for length, while snap gauge is a tool used to measure the thickness or diameter of an object.

• Micrometre is also known as a micron and is equal to one-millionth of a meter.

• Snap gauge is used in manufacturing to ensure the accuracy of machined parts.

• Snap gauge can be used to measure the thickness of paper, the diameter of a wire, or the width of a gap.

• Both micrometre and snap gauge are commonly used in engineering and manufacturing industrie...read more

The minimum limit of a vernier caliper is the smallest measurement it can accurately measure.

• The minimum limit of a vernier caliper is typically 0.02 mm or 0.001 inches.

• This means that the vernier caliper can accurately measure up to 0.02 mm or 0.001 inches.

• Any measurement smaller than the minimum limit may not be accurate or reliable.

A petrol engine is an internal combustion engine that uses petrol as fuel to power the vehicle.

• Petrol engines are commonly used in cars, motorcycles, and small aircraft.

• They work by compressing a mixture of petrol and air in a cylinder, which is then ignited by a spark plug.

• The resulting explosion pushes a piston, which turns a crankshaft and powers the vehicle.

• Petrol engines are known for their high power output and quick acceleration.

• However, they are less fuel-efficient th...read more

The unit of pressure is Pascal (Pa)

• Pressure is defined as force per unit area

• The SI unit of force is Newton (N) and area is square meter (m²)

• 1 Pascal is equal to 1 Newton per square meter (N/m²)

• Other common units of pressure include atmosphere (atm), bar (bar), and pounds per square inch (psi)
