Q3. Difference between 2 stroke and 4 stroke engine?
Ans. 
2 stroke engines have power strokes every revolution, while 4 stroke engines have power strokes every other revolution.
• 2 stroke engines have a simpler design with fewer moving parts compared to 4 stroke engines.

• 2 stroke engines require a fuel-oil mixture for lubrication, while 4 stroke engines have a separate oil reservoir.

• 2 stroke engines produce more pollution due to incomplete combustion, while 4 stroke engines are ...read more

Q4. Difference between petrol and diesel engine
Ans. 
Petrol engines use spark ignition, while diesel engines use compression ignition.
• Petrol engines use a spark plug to ignite the fuel-air mixture, while diesel engines rely on compression to ignite the fuel.

• Petrol engines are lighter and more responsive, while diesel engines are more fuel efficient and have higher torque.

• Petrol engines are typically used in cars and motorcycles, while diesel engines are commonly found in

Q2. Y should we measure in mm
Ans. 
Measuring in mm provides a more precise and accurate measurement compared to other units.
• Millimeters are a smaller unit of measurement, allowing for more precise measurements.

• Using mm can help avoid rounding errors that may occur with larger units like centimeters or meters.

• Many mechanical components are designed and manufactured with measurements in mm for accuracy.

• International standards often use mm as the preferred...read more

Q2. What is the theory of failure and how to determine the FEM result when we get result was passed.
Ans. 
Theory of failure is a concept used in engineering to predict the failure of materials under different loading conditions.
• Theory of failure helps engineers understand how materials will behave under stress and strain.

• Different theories of failure include maximum normal stress theory, maximum shear stress theory, and maximum strain energy theory.

• Finite Element Method (FEM) is a numerical technique used to analyze stress...read more

Q3. Draw the ss curve and define the terms.
Ans. 
The SS curve is a stress-strain curve used to analyze the behavior of a material under stress.
• The SS curve, also known as the stress-strain curve, shows the relationship between stress (force applied per unit area) and strain (deformation) of a material.

• It typically consists of three main regions: elastic deformation, plastic deformation, and fracture.

• The elastic region is where the material deforms elastically and ret...read more
