Q1. Tell about compressure working principle.
Ans. 
A compressor works by increasing the pressure of a gas to compress it into a smaller volume.
• Compressors use a motor to drive a piston or rotor that compresses the gas.

• The compressed gas is then stored in a tank or released for use in various applications.

• Common types of compressors include reciprocating, rotary screw, and centrifugal compressors.

Q2. What is the method of forging
Ans. 
Forging is a manufacturing process involving the shaping of metal using localized compressive forces.
• Heating the metal to a high temperature to make it more malleable

• Applying compressive forces to shape the metal into the desired form

• Cooling the forged metal to strengthen it

• Types of forging include open-die forging, closed-die forging, and seamless rolled ring forging
