Q3. What is fatigue and what is creep in materials
Ans. 
Fatigue is the weakening of a material due to repeated loading, while creep is the gradual deformation of a material under constant stress.
• Fatigue is the process of progressive and localized structural damage that occurs when a material is subjected to cyclic loading.

• Creep is the time-dependent deformation of a material under constant load or stress.

• Fatigue failure is often characterized by crack initiation and propaga...read more

Q4. What are the different types of Steel making
Ans. 
Different types of steel making include basic oxygen furnace, electric arc furnace, and open hearth furnace.
• Basic Oxygen Furnace (BOF) - uses oxygen to reduce the carbon content in the steel

• Electric Arc Furnace (EAF) - uses electricity to melt scrap steel and produce new steel

• Open Hearth Furnace - uses a fuel-air mixture to heat the steel and remove impurities

• Other methods include Bessemer process, direct reduced iron,

Q6. What is SN curve ?
Ans. 
SN curve is a graphical representation of the relationship between stress and fatigue life of a material.
• SN curve shows the number of cycles to failure (N) against the applied stress (S).

• It helps in determining the fatigue life of a material under different stress levels.

• Materials with higher fatigue strength have a steeper slope on the SN curve.

• SN curves are commonly used in engineering to predict the durability of ma

Q7. What is the composition of pigiron
Ans. 
Pig iron is an intermediate product of the iron industry, made by smelting iron ore in a blast furnace.
• Pig iron is typically around 92-94% iron, with varying amounts of carbon, silicon, manganese, sulfur, and phosphorus.

• It is brittle and not suitable for use in its raw form, but can be further processed into wrought iron or steel.

• The carbon content of pig iron gives it a high carbon equivalent, making it ideal for cast...read more

Q8. What is lever rule?
Ans. 
Lever rule is a principle used in material science to determine the relative amounts of two phases in a two-phase system.
• Lever rule is used to calculate the fraction of each phase in a two-phase system based on the weight or volume percentages of the phases.

• It is commonly used in metallurgy, ceramics, and other material science fields.

• The lever rule equation is: L = (C - A) / (B - A), where L is the fraction of one pha...read more

Q1. Different between kinematics and dynamic viscosity
Ans. 
Kinematic viscosity is the ratio of dynamic viscosity to density, representing the fluid's resistance to flow. Dynamic viscosity is the measure of a fluid's internal resistance to flow.
• Kinematic viscosity is dynamic viscosity divided by density

• Kinematic viscosity is measured in square meters per second (m^2/s)

• Dynamic viscosity is measured in pascal-seconds (Pa.s) or centipoise (cP)

• Dynamic viscosity represents the fluid...read more
