Berger Paints Interview Questions and Answers

First angle and third angle projection are two different methods used in technical drawing to represent a 3D object on a 2D surface.

• First angle projection is commonly used in Europe and Asia, while third angle projection is commonly used in North America.

• In first angle projection, the object is placed in the first quadrant and the views are projected onto the planes surrounding the object.

• In third angle projection, the object is placed in the third quadrant and the views are ...read more

Towing and taxing are processes used in aviation to move aircraft on the ground.

• Towing involves using a tug vehicle to move an aircraft from one location to another on the ground.

• Taxing refers to the movement of an aircraft under its own power on the ground, typically to and from the runway.

• Both towing and taxing require coordination between ground crew and pilots to ensure safety and efficiency.

• Examples: Towing an aircraft to a maintenance hangar, taxing to the runway for ta...read more

The calling mach number is the ratio of the speed of an object to the speed of sound in the medium through which the object is moving.

• It is used in aerodynamics to determine the compressibility effects on the flow around an object.

• A calling mach number of 1 means the object is traveling at the speed of sound.

• Supersonic speeds have calling mach numbers greater than 1, while subsonic speeds have calling mach numbers less than 1.

Basic principles of aircraft flying involve lift, thrust, drag, and weight.

• Lift is generated by the wings as air flows over them at a higher speed than below.

• Thrust is provided by the engines to move the aircraft forward.

• Drag is the resistance encountered by the aircraft as it moves through the air.

• Weight is the force of gravity acting on the aircraft.

• To maintain level flight, lift must equal weight and thrust must equal drag.

Supersonic speed in aircraft refers to speeds greater than the speed of sound.

• Supersonic speeds are typically achieved by military jets and some commercial aircraft like the Concorde.

• At supersonic speeds, shock waves form around the aircraft, causing a sonic boom.

• Supersonic flight requires specialized aerodynamics and materials to withstand the high temperatures and pressures.

• Supersonic aircraft like the SR-71 Blackbird can reach speeds of over Mach 3.

• Supersonic travel is cur...read more
