Q2. Working of micrometre
Ans. 
Micrometre is a precision measuring instrument used to measure small distances accurately.
• Micrometre consists of a stationary anvil and a movable spindle.

• The object to be measured is placed between the anvil and spindle, and the spindle is turned to make contact with the object.

• The measurement is read from the scale on the sleeve and thimble of the micrometre.

• Micrometres are commonly used in engineering and manufacturi...read more

Q3. What is degree of freedom
Ans. 
Degree of freedom refers to the number of independent variables or parameters that can vary in a system.
• Degree of freedom is the number of variables that can be changed independently without affecting the overall system.

• In mechanics, a rigid body in a plane has 3 degrees of freedom - two translations and one rotation.

• In thermodynamics, a simple compressible substance has 2 degrees of freedom - temperature and pressure.

Q4. Types of forging , rolling
Ans. 
Forging and rolling are two common metalworking processes used to shape metal into desired forms.
• Forging involves shaping metal by applying compressive forces, typically using a hammer or press.

• Types of forging include open-die forging, closed-die forging, and impression-die forging.

• Rolling involves passing metal between rollers to reduce thickness or change shape.

• Types of rolling include hot rolling, cold rolling, and

Q2. 2. What is the working principle of diesel cycle?
Ans. 
Diesel cycle is a thermodynamic cycle used in diesel engines to convert heat into work.
• Air is compressed in the cylinder, causing its temperature to rise.

• Fuel is injected into the cylinder, igniting due to the high temperature.

• The expanding gases push the piston, converting heat into mechanical energy.

• Exhaust gases are expelled from the cylinder.

• Diesel cycle is more efficient than Otto cycle used in gasoline engines.
