Answer:
Rage pressure:
The rage pressure in terms of engineering is the protected shield hard plastic shell and made up of the hard material that is basically used in the protection.
It is the effective material and used in the sewing machine so the pressure developed due to the hard material is known as rage pressure and it has strong elasticity.
Absolute pressure:
The pressure which is relative to the perfect vacuum is known as absolute pressure. The absolute pressure is basically measured against the atmospheric pressure.
The absolute pressure is defined as the total pressure in the fluid at the point is equal to the sum of the atmospheric pressure and gauge.
