Maintenance Mechanic Interview Questions and Answers
Q1. What is the transformer?
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, known as the primary and secondary coils, which are wrapped around a magnetic core.
When an AC voltage is applied to the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.

Q2. What is the bearing?
A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.
Bearings are used to support rotating shafts and reduce friction between moving parts.
They come in various types such as ball bearings, roller bearings, and plain bearings.
Bearings are commonly used in machines such as engines, turbines, and pumps.
Proper lubrication is important for the longevity and performance of bearings.
Q3. What is the torque ?
Torque is a measure of the twisting force that causes rotation.
Torque is measured in units of force multiplied by distance, such as newton-meters or pound-feet.
It is important in mechanical systems to ensure that the correct amount of torque is applied to bolts and other fasteners to prevent failure or damage.
Examples of tools used to measure torque include torque wrenches and torque screwdrivers.
