Prakharah JEE & NEET Academy Interview Questions and Answers

Heat treatment processes are used to alter the physical and mechanical properties of materials through heating and cooling.

• Heat treatment processes involve heating and cooling of materials to alter their properties

• Types of heat treatment processes include annealing, quenching, tempering, and normalizing

• Annealing involves heating the material to a specific temperature and then cooling it slowly to make it softer and more ductile

• Quenching involves cooling the material rapidly t...read more

Pressure cooker is a sealed pot that uses high pressure to cook food quickly.

• Pressure cooker has a sealed lid that traps steam inside, increasing pressure and temperature.

• The high pressure and temperature cook food faster than traditional methods.

• Pressure cookers are commonly used for cooking rice, beans, and stews.

• They are also used for canning food.

• Pressure cookers have safety features to prevent explosions, such as pressure release valves.

• The first pressure cooker was inve...read more

Coupling is the degree of interdependence between two or more systems or components.

• Coupling refers to the extent to which one component depends on another component.

• There are two types of coupling: loose coupling and tight coupling.

• Loose coupling means that the components are independent of each other and can function separately.

• Tight coupling means that the components are highly dependent on each other and cannot function separately.

• Examples of loose coupling include a clie...read more

Welding is a process of joining two or more metal parts by heating the surfaces to their melting points and allowing them to cool and fuse together.

• There are several types of welding such as MIG, TIG, Stick, and Flux-Cored welding.

• MIG welding uses a wire electrode and a shielding gas to create a strong bond between the metals.

• TIG welding uses a tungsten electrode and a filler metal to create a precise and clean weld.

• Stick welding uses a consumable electrode coated in flux to ...read more

A visual representation of a process showing the sequence of steps and decision points.

• Shows the flow of materials, information, and actions

• Used to identify potential problems and inefficiencies

• Commonly used in engineering and manufacturing

• May include symbols and labels to indicate specific actions or equipment
