10+ Inncircles Technologies Interview Questions and Answers

If pressure valve fails in boiler, shut down the boiler immediately and isolate it from the system.

• Shut down the boiler immediately to prevent any further damage.

• Isolate the boiler from the system to prevent any pressure build-up.

• Inspect the pressure valve to determine the cause of failure.

• Replace the pressure valve with a new one.

• Test the new pressure valve to ensure it is functioning properly before restarting the boiler.

An aeroplane consists of several basic parts that work together to enable flight.

• The wings generate lift and provide stability

• The fuselage houses the cockpit, passengers, and cargo

• The engines provide thrust to move the plane forward

• The tail section includes the horizontal stabilizer and vertical fin for directional control

• The landing gear allows the plane to take off and land

• The avionics system includes instruments and electronics for navigation and communication

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 shield to reflect the heat away from the pipe

A water rocket works by pressurizing water and air inside a bottle, creating thrust that propels the rocket upwards.

• Water and air are added to a plastic bottle, with the air pressurized using a pump or compressed air source.

• When the bottle is released, the pressurized air forces the water out of the nozzle, creating a reaction force that propels the rocket upwards.

• The height the rocket reaches depends on factors such as the amount of water and air used, the size of the bottle...read more

Micromaterials refer to materials with microscale dimensions, typically less than 100 micrometers.

• Micromaterials have unique properties due to their small size, such as increased surface area to volume ratio and altered mechanical, electrical, and optical properties.

• Examples of micromaterials include microelectromechanical systems (MEMS), microfluidic devices, and microscale sensors.

• Research in micromaterials has applications in fields such as biotechnology, electronics, and ...read more

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 affected by factors such as temperature and strain rate.

Designed a chair for a class that is comfortable, durable, and ergonomic.

• Consider the height of the desk and the average height of the students

• Use materials that are sturdy and easy to clean

• Incorporate lumbar support and adjustable features for comfort

• Add armrests for additional support

• Ensure the chair has a non-slip base for safety

MR Braking stands for Magnetic Resistance Braking. It is a type of braking system used in trains and other vehicles.

• MR Braking uses magnetic fields to slow down or stop a vehicle.

• It is commonly used in trains as it provides a smooth and efficient braking system.

• The braking force is generated by the resistance between the magnetic field and the conductive material on the train's wheels.

• MR Braking is also used in roller coasters and other amusement park rides.

• It is a safer and ...read more

Basic laws of thermodynamics

• First law: Energy cannot be created or destroyed, only transferred or converted

• Second law: Entropy of a closed system always increases over time

• Third law: Absolute zero cannot be reached

• Examples: car engine, refrigerator, power plant
