Q2. Explain heat treatment
Ans. 
Heat treatment is a process used to alter the physical and sometimes chemical properties of a material through controlled heating and cooling.
• Heat treatment involves heating a material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.

• The purpose of heat treatment is to improve the material's hardness, strength, toughness, ductility, and oth...read more

Q3. How to increase corrosion resistance in steel
Ans. 
To increase corrosion resistance in steel, various methods such as coating, alloying, and controlling environmental factors can be employed.
• Applying protective coatings such as zinc, paint, or polymer can help prevent corrosion

• Alloying steel with elements like chromium, nickel, or copper can improve corrosion resistance

• Controlling environmental factors such as humidity, temperature, and pH levels can also reduce corros

Q4. What is formula for leaf spring and cylindrical spring
Ans. 
The formula for leaf spring is based on the material properties and geometry, while the formula for cylindrical spring is based on Hooke's Law.
• Leaf spring formula involves parameters like material modulus of elasticity, width, thickness, and length.

• Cylindrical spring formula is based on Hooke's Law: F = kx, where F is the force, k is the spring constant, and x is the displacement.

Q5. Explain otto cycle
Ans. 
The Otto cycle is a theoretical thermodynamic cycle that describes the functioning of a typical spark ignition piston engine.
• Consists of four processes: isentropic compression, constant volume heat addition, isentropic expansion, and constant volume heat rejection

• Used in gasoline engines to convert chemical energy into mechanical work

• Higher efficiency compared to Diesel cycle due to higher compression ratio

• Named after ...read more
