Q3. Draw a stress strain curve
Ans. 
A stress-strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.
• The curve typically starts at the origin, representing the material's elastic region where it deforms elastically under stress.

• As stress increases, the material reaches its yield point where it begins to deform plastically.

• The curve continues to the ultimate tensile strength, the maximum stress t...read more

Q4. Represent all the area under the graph labelled
Ans. 
The area under a graph represents the total value of the function over a given interval.
• Calculate the integral of the function to find the area under the graph

• The area under the graph can be positive or negative depending on the function

• Use geometric shapes like rectangles or trapezoids to estimate the area under the graph

Q2. . different forces acting on a moving cycle and force analysis . newtonian and non newtonian fluids .why tyres are made of rubber and not steel
Ans. 
Forces acting on a moving cycle, Newtonian vs non-Newtonian fluids, and why tires are made of rubber.
• Forces on a moving cycle include friction, air resistance, and gravity.

• Newtonian fluids have constant viscosity, while non-Newtonian fluids change viscosity with stress.

• Tires are made of rubber for flexibility, grip, and shock absorption.

• Rubber tires provide better traction and a smoother ride compared to steel tires.

Q3. Howadiabatic and constant volume processes are achieved in practical
Ans. 
Adiabatic and constant volume processes are achieved in practical by controlling heat transfer and volume change respectively.
• Adiabatic process is achieved by insulating the system to prevent heat transfer with the surroundings.

• Constant volume process is achieved by using a closed container where the volume remains constant during the process.

• Examples include adiabatic compression in a gas turbine engine and constant v

Q4. Why priming is neede in the pumps
Ans. 
Priming is needed in pumps to remove air and create a vacuum, ensuring proper functioning and preventing damage.
• Priming removes air from the pump, allowing it to create a vacuum and start pumping efficiently.

• It helps prevent cavitation, which can damage the pump by causing vibrations and erosion.

• Priming is essential for self-priming pumps to start pumping without manual intervention.

• Examples of priming methods include ...read more

Q5. What is NPSH of pumps
Ans. 
NPSH stands for Net Positive Suction Head, it is a measure of the pressure available at the suction port of a pump.
• NPSH is important for determining if a pump will operate properly without cavitation.

• It is calculated by subtracting the vapor pressure of the liquid being pumped from the total suction head of the pump.

• NPSH is typically provided by the pump manufacturer and must be considered when selecting a pump for a s
