- Q1. Types of bearing ?
- Ans.
Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.
Ball bearings use balls to reduce friction between two surfaces (e.g. deep groove ball bearings)
Roller bearings use cylindrical rollers to support heavy loads (e.g. tapered roller bearings)
Plain bearings have a simple design with no rolling elements (e.g. bushings)
Fluid bearings use a fluid film to support rotating shafts (e.g.
- Q2. Types of gears ?
- Ans.
Types of gears include spur gears, helical gears, bevel gears, worm gears, rack and pinion gears, and planetary gears.
Spur gears have straight teeth and are the simplest type of gear.
Helical gears have angled teeth for smoother and quieter operation.
Bevel gears have cone-shaped teeth and are used to change the direction of rotation.
Worm gears have a screw-like appearance and are used for high torque applications.

- Ans.
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).
Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.
They are made up of diodes, which allow current to flow in only one direction.
Rectifiers can be half-wave or full-wave, depending on the number of diodes used.
Examples of rectifiers include bridge rectifiers, vacuum tube rectifiers, and soli
- Q3. What is scr and how it work
- Ans.
SCR stands for Selective Catalytic Reduction. It is a technology used to reduce nitrogen oxide emissions from diesel engines.
SCR is a process that uses a catalyst to convert nitrogen oxides (NOx) into nitrogen (N2) and water (H2O).
It involves injecting a urea-based solution, known as diesel exhaust fluid (DEF), into the exhaust stream.
The DEF reacts with the NOx in the presence of the catalyst, breaking it down into ha...
