Q1. Different between Forgings and casting
Ans. 
Forging involves shaping metal through compression, while casting involves pouring molten metal into a mold.
• Forging involves shaping metal through compressive forces, while casting involves pouring molten metal into a mold to solidify.

• Forging typically results in stronger and more durable parts compared to casting.

• Forging is a more precise process that allows for tighter tolerances, while casting is more suitable for c...read more

Q2. What is the forgings
Ans. 
Forgings are metal components that are shaped by compressive forces, typically through hammering or pressing.
• Forgings are typically stronger and more reliable than castings or machined parts.

• Common forging processes include open-die forging, closed-die forging, and ring rolling.

• Examples of forged components include crankshafts, connecting rods, and gears.

• Forgings are often used in industries such as automotive, aerospa

Q4. Process in casting
Ans. 
Process in casting involves pouring molten metal into a mold to create a desired shape.
• Mold preparation is crucial for successful casting

• Molten metal is poured into the mold cavity

• Cooling and solidification of the metal takes place inside the mold

• The casting is removed from the mold and finished as needed

Q5. Process in forging
Ans. 
Forging is a manufacturing process where metal is shaped by applying compressive forces using a hammer or press.
• Metal is heated to a high temperature to make it more malleable

• The metal is then placed on a die and struck with a hammer or pressed to shape it

• Forging can be done using different techniques like open-die forging, closed-die forging, and impression-die forging

Q1. Formula for 3rd law of thermodynamics
Ans. 
The formula for the 3rd law of thermodynamics is S = 0 as temperature approaches absolute zero.
• The third law of thermodynamics states that the entropy of a perfect crystal at absolute zero is zero.

• The formula for the third law of thermodynamics is S = 0 as the temperature approaches absolute zero.

• This law implies that it is impossible to reach absolute zero temperature.

• The third law is often used to calculate the entro

Q2. Heat engine types
Ans. 
Heat engines are devices that convert heat energy into mechanical work. There are several types including internal combustion engines, steam engines, and gas turbines.
• Internal combustion engines: use combustion of fuel within the engine to generate power (e.g. gasoline engines)

• Steam engines: use steam to generate power through a piston and cylinder arrangement (e.g. steam locomotives)

• Gas turbines: use combustion of fue...read more
