Q1. Bending moment diagram
Ans. 
Explanation of bending moment diagram
• Bending moment diagram is a graphical representation of the variation of bending moment along the length of a beam

• It is used to determine the maximum bending moment and the location of the maximum bending moment in a beam

• The area under the bending moment diagram represents the shear force acting on the beam

• The bending moment at any point on the beam can be calculated by taking the a...read more

Q2. Stress strain graph of stainless steel
Ans. 
Stress-strain graph of stainless steel shows high strength and ductility.
• Stainless steel has a linear elastic region followed by a yield point and then strain hardening.

• The ultimate tensile strength of stainless steel is higher than mild steel.

• Stainless steel exhibits a significant amount of plastic deformation before failure.

• The area under the stress-strain curve represents the energy absorbed by the material during d

Q3. Design parameters of making a equipment
Ans. 
Design parameters are the specific requirements that an equipment must meet to function effectively.
• Design parameters include factors such as size, weight, power consumption, and operating temperature.

• Other important parameters may include durability, reliability, and ease of maintenance.

• For example, when designing a car engine, parameters such as horsepower, torque, and fuel efficiency must be considered.

• Similarly, wh...read more

Q5. SS304 and SS316 material usage and application
Ans. 
SS304 and SS316 are both austenitic stainless steels with different compositions and properties.
• SS304 contains 18% chromium and 8% nickel, while SS316 contains 16% chromium, 10% nickel, and 2% molybdenum.

• SS316 is more corrosion-resistant than SS304, especially in chloride environments.

• SS304 is commonly used in food processing equipment, kitchen appliances, and chemical containers, while SS316 is used in marine applicat...read more
