Q1. Draw stress strain curve for ductile and brittle material
Ans. 
Ductile materials have a gradual stress-strain curve with noticeable yielding before fracture, while brittle materials have a sudden fracture without much deformation.
• Ductile materials show a gradual increase in stress with strain, followed by necking and eventual fracture.

• Brittle materials have a steep stress-strain curve with minimal plastic deformation before sudden fracture.

• Examples of ductile materials include ste...read more

Q2. Draw shear force diagram for cantilever beam
Ans. 
Shear force diagram for a cantilever beam shows the variation of shear force along the length of the beam.
• Start with the free end of the cantilever beam and draw the reactions at the fixed end.

• Calculate the shear force at different points along the beam using the equations of equilibrium.

• Plot the shear force values on the diagram with appropriate scales and directions.

• The shear force diagram will show the variation of ...read more

Q3. What is condensation
Ans. 
Condensation is the process by which a gas or vapor turns into a liquid.
• Occurs when warm air cools down and cannot hold as much moisture

• Commonly seen on windows on a cold day

• Can be a result of humidity in the air

Q4. Modes of heat transfer in engine
Ans. 
Modes of heat transfer in engine include conduction, convection, and radiation.
• Conduction: Heat transfer through direct contact between solid surfaces, such as engine components.

• Convection: Heat transfer through the movement of fluids, such as coolant circulating in the engine.

• Radiation: Heat transfer through electromagnetic waves, such as heat radiating from the engine.

Q5. Ac working principle explain
Ans. 
AC works by removing heat from the air inside a space and transferring it outside, cooling the indoor air.
• AC units use refrigerant to absorb heat from indoor air

• The refrigerant then moves to the outdoor unit where it releases the heat

• The cooled refrigerant returns to the indoor unit to absorb more heat

• The process continues until the desired temperature is reached

Q1. What is diesel engine
Ans. 
A diesel engine is an internal combustion engine that uses compression ignition to burn fuel.
• Diesel engines are commonly used in trucks, buses, ships, and some cars.

• They are more fuel efficient than gasoline engines.

• Diesel engines do not have spark plugs; instead, they rely on the heat generated by compressing air in the combustion chamber to ignite the fuel.

• Diesel engines produce more torque at lower RPMs compared to

Q2. What is flywheel
Ans. 
A flywheel is a mechanical device used to store rotational energy and smooth out fluctuations in speed of a machine.
• Flywheels are commonly used in engines to maintain a consistent speed of rotation.

• They store energy during the power stroke and release it during the compression stroke.

• Flywheels are also used in some industrial processes to regulate the speed of machinery.
