Q2. Bending moment calculation
Ans. 
Bending moment calculation involves determining the internal bending forces in a structure.
• Bending moment is the algebraic sum of moments about the neutral axis of a cross section of a beam or other structural element.

• It is calculated using the formula: M = F * d, where M is the bending moment, F is the force applied, and d is the perpendicular distance from the force to the neutral axis.

• Bending moment diagrams are use...read more

Q2. Difference b/w petrol engine & 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 more common in cars and motorcycles, while diesel engines are often used in trucks

Q3. What is meant by LNTD
Ans. 
LNTD stands for Logarithmic Mean Temperature Difference.
• LNTD is a term used in heat transfer calculations to determine the overall temperature difference between two fluids in a heat exchanger.

• It is calculated using the formula LNTD = (ΔT1 - ΔT2) / ln(ΔT1 / ΔT2), where ΔT1 and ΔT2 are the temperature differences at the two ends of the heat exchanger.

• LNTD is important in designing efficient heat exchangers to maximize h...read more

Q2. Which type of ic engine
Ans. 
Internal combustion engines are classified into two main types: spark ignition (SI) engines and compression ignition (CI) engines.
• Spark ignition (SI) engines use a spark plug to ignite the fuel-air mixture, commonly found in gasoline engines.

• Compression ignition (CI) engines rely on the heat generated by compressing the air in the cylinder to ignite the fuel, commonly found in diesel engines.

• Each type of engine has its...read more
