Autofit Interview Questions and Answers

EMF stands for electromotive force, which is the voltage generated by a source such as a battery. Volt is the unit of measurement for voltage, while watt is the unit of measurement for power.

• EMF is the voltage generated by a source of electrical energy, such as a battery

• Volt is the unit of measurement for voltage, representing the potential difference between two points in a circuit

• Watt is the unit of measurement for p...read more

Hydraulic machines use fluid power to perform work, while hydraulic machines are machines that utilize hydraulic power.

• Hydraulic machines use fluid power to generate force and motion, such as hydraulic presses and hydraulic cylinders.

• Hydraulic machines are machines that utilize hydraulic power, such as excavators and forklifts.

• Hydraulic machines are often used in heavy-duty industrial applications, while hydraulic mach...read more

A machine is a device that uses energy to perform a specific task or function.

• A machine is typically made up of various components that work together to achieve a desired outcome

• Machines can range from simple tools like a hammer to complex systems like a computer

• Examples of machines include cars, washing machines, and robots

2 stroke engines have a power cycle with two strokes (up and down) of the piston in one revolution, while 4 stroke engines have four strokes (intake, compression, power, exhaust) in two revolutions.

• 2 stroke engines have a simpler design with fewer moving parts compared to 4 stroke engines

• 2 stroke engines require a mixture of oil and fuel for lubrication, while 4 stroke engines have a separate oil reservoir for lubricat...read more

The principle of least count is the smallest measurement that can be made by a measuring instrument.

• It is the smallest increment that can be measured by the instrument.

• It is determined by the precision of the instrument.

• For example, a ruler with markings at every millimeter has a least count of 1 mm.

• In a digital caliper with a resolution of 0.01 mm, the least count is 0.01 mm.

Vernier caliper is a measuring tool used to take precise measurements, with a vernier scale providing additional accuracy.

• Vernier caliper is a tool used for measuring dimensions accurately.

• It consists of a main scale and a vernier scale for more precise readings.

• The vernier scale allows for measurements to be taken to a higher degree of accuracy than just the main scale alone.

• Commonly used in engineering, manufacturing...read more
