Heat and Control Interview Questions and Answers

Q1. Elasticity formula
Ans. 
Elasticity formula relates to the ability of a material to deform under stress and return to its original shape when the stress is removed.
• Elasticity formula is typically represented as stress divided by strain: E = σ / ε

• Stress is the force applied to a material per unit area, while strain is the resulting deformation of the material.

• The elasticity formula is used to determine how much a material will deform under a gi...read more

Q2. What are the differences between the 304, 304L, and 316 stainless steel grades?
Ans. 
304, 304L, and 316 stainless steel grades differ in their carbon content, corrosion resistance, and applications.
• 304 stainless steel contains 18% chromium and 8% nickel, while 304L has a lower carbon content to prevent sensitization during welding.

• 316 stainless steel contains 16-18% chromium, 10-14% nickel, and 2-3% molybdenum for increased corrosion resistance, making it suitable for marine environments.

• 304 and 304L a...read more

Q3. What is the formula for calculating stress and strain in materials?
Ans. 
The formula for calculating stress and strain in materials is based on Hooke's Law.
• Stress (σ) = Force (F) / Area (A)

• Strain (ε) = Change in length (ΔL) / Original length (L)

• Hooke's Law: Stress = Young's Modulus x Strain

• Example: If a force of 100 N is applied to a material with a cross-sectional area of 2 m^2, the stress would be 50 N/m^2
