Different types of fit include clearance fit, interference fit, and transition fit.
Clearance fit: parts are designed to have a gap between them, allowing for easy assembly and disassembly.
Interference fit: parts are designed to be pressed or forced together, creating a tight and secure fit.
Transition fit: parts have a small amount of overlap, creating a balance between clearance and interference fit.
Examples include pi...

The motor used in fans is typically an induction motor.
Induction motors are commonly used in fans due to their simplicity, reliability, and cost-effectiveness.
These motors work on the principle of electromagnetic induction to generate rotational motion.
Examples of induction motors used in fans include single-phase and three-phase motors.
Fan motors are usually designed to be energy-efficient and have varying speeds for
A fuse is a safety device that protects electrical circuits from overcurrent. The type of pins used depend on the specific fuse design.
A fuse is a thin wire or strip of metal that melts when excessive current flows through it, breaking the circuit and preventing damage.
There are different types of fuses such as cartridge fuses, blade fuses, and glass-tube fuses, each with their own unique pin configurations.
Cartridge f...
I applied via Campus Placement and was interviewed in Oct 2024. There was 1 interview round.
The motor used in fans is typically an induction motor.
Induction motors are commonly used in fans due to their simplicity and reliability.
The most common type of induction motor used in fans is the single-phase induction motor.
Some high-end fans may use brushless DC (BLDC) motors for energy efficiency and quiet operation.
A fuse is a safety device that protects electrical circuits from overcurrent. Types of pins in a fuse include blade, cartridge, and glass.
Blade fuses have flat blades that fit into slots in the fuse block
Cartridge fuses are cylindrical in shape and have metal end caps
Glass fuses have a glass tube with metal caps on both ends

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.
Ohm's law is expressed as V = I * R, where V is the voltage, I is the current, and R is the resistance.
It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.
For example, if a circuit has a vol...
An internal combustion engine (IC engine) is a type of engine that generates power by burning fuel inside the engine itself.
IC engines are commonly used in vehicles such as cars, motorcycles, and trucks.
They work by igniting fuel-air mixture inside a combustion chamber to create controlled explosions.
The energy from these explosions is converted into mechanical energy to drive the vehicle.
There are different types of I...
Hydrotreating and hydrocracking are two refining processes used to improve the quality of petroleum products.
Hydrotreating involves the use of hydrogen and a catalyst to remove impurities such as sulfur, nitrogen, and metals from crude oil or other feedstocks.
Hydrotreating helps to produce cleaner fuels with lower sulfur content, which is important for meeting environmental regulations.
Hydrocracking is a more severe pr...
