Question

Accepted Answer

Stress, strain, automobile, IC engine, SI engine, four-stroke engine, and two-stroke engine are all related to mechanical engineering.

Stress is the force applied per unit area, while strain is the deformation caused by stress.
An automobile is a vehicle that is designed to transport people or goods on roads.
An IC engine is an internal combustion engine that converts chemical energy into mechanical energy.
An SI engine is a type of IC engine that uses a spark plug to ignite the fuel mixture.
The main difference between IC engine and SI engine is the method of ignition.
A four-stroke engine completes four strokes in one cycle, while a two-stroke engine completes two strokes in one cycle.
Examples of four-stroke engines include most car engines, while examples of two-stroke engines include some motorcycles and lawnmowers.

Accepted Answer

It has one revolution of the crankshaft during one power stroke.	It has two revolutions of the crankshaft during one power stroke.
It generates high torque.	It generates less torque.
It uses a port for the fuel’s outlet and inlet.	It uses valves for the fuel’s outlet and inlet.
Its engines result in lesser thermal efficiency.	Its engines result in higher thermal efficiency.
It has a larger ratio in terms of power to weight.	It has a lesser ratio in terms of power to weight.
It generates more smoke and shows less efficiency.	It generates less smoke and shows more efficiency.
Requires more lubricating oil as some oil burns with the fuel.	Requires less lubricating oil.
Due to poor lubrication, more wear and tear occurs.	Less wear and tear occurs.
Engines are cheaper and are simple to manufacture.	Engines are expensive due to lubrication and valves and are tough to manufacture.
Engines are basically lighter and noisier.	Engines are basically heavier because their flywheel is heavy and less noisy
