Q4. Defination of stress
Ans. 
Stress is the force per unit area that a material experiences when subjected to an external load.
• Stress is a measure of the internal forces within a material.

• It is calculated as force per unit area.

• Stress can cause deformation or failure of a material.

• There are different types of stress, such as tensile, compressive, and shear stress.

• Examples of stress include the weight of a book on a table, the force applied to a bri...read more

Q2. Stress strain Curve of aluminium
Ans. 
Aluminium stress strain curve shows its elastic and plastic deformation behavior under stress.
• Aluminium has a linear elastic region up to a certain point, beyond which it undergoes plastic deformation.

• The yield strength of aluminium is around 40-90 MPa.

• Ultimate tensile strength of aluminium is around 90-200 MPa.

• Aluminium has a low modulus of elasticity compared to steel.

• The stress strain curve of aluminium can be affec...read more

Q6. How we cool a pipe in a chamber without using coolent
Ans. 
Cooling a pipe in a chamber without coolant
• Use natural convection by placing the pipe vertically and allowing air to circulate around it

• Use a heat sink to absorb the heat from the pipe

• Use a thermoelectric cooler to create a temperature gradient and cool the pipe

• Use a phase change material to absorb the heat from the pipe

• Use a heat exchanger to transfer the heat from the pipe to a cooler fluid or gas

• Use a radiation shie
