Ans. 
The grade of coal in a coal handling plant is determined by its carbon content and calorific value.
• Coal grades are classified based on their carbon content and calorific value, such as anthracite, bituminous, sub-bituminous, and lignite.

• Superfinishing processes like honing and lapping are used to achieve high precision and smooth surface finishes on metal parts.

• Casting involves pouring molten metal into a mold to creat...read more

It consists of 2 sections reasoning and core.

Q1. What are SFD and BMD
Ans. 
SFD stands for Shear Force Diagram and BMD stands for Bending Moment Diagram.
• SFD and BMD are graphical representations of the internal forces and moments in a structural element.

• SFD shows the variation of shear force along the length of the element.

• BMD shows the variation of bending moment along the length of the element.

• These diagrams are commonly used in structural analysis and design.

• They help engineers understand t...read more

Q2. Explain about different types of modes of heat transfer
Ans. 
There are three modes of heat transfer: conduction, convection, and radiation.
• Conduction is the transfer of heat through direct contact between objects or substances.

• Convection is the transfer of heat through the movement of fluids or gases.

• Radiation is the transfer of heat through electromagnetic waves.

• Examples of conduction include touching a hot stove or holding a metal spoon in hot soup.

• Examples of convection inclu...read more

Q4. Thermodynamic laws
Ans. 
Thermodynamic laws govern the behavior of energy in systems.
• The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed.

• The second law of thermodynamics states that the entropy of an isolated system always increases over time.

• The third law of thermodynamics states that as the temperature approaches absolute zero, the entropy of a system approaches a minimum value.
