Q2. What is work in piston
Ans. 
Work in piston refers to the force exerted by the expanding gases on the piston during the power stroke.
• During the power stroke, fuel is ignited in the combustion chamber, which creates a high-pressure gas that pushes the piston down.

• The force exerted by the expanding gases on the piston is what produces the work output of the engine.

• The work done by the piston is transferred to the crankshaft, which converts the linea...read more
