Fabcon Design Engineer Interview Questions and Answers

Q1. What is first angle and third angle
Ans. 
First angle and third angle are two different methods of representing orthographic projections in engineering drawings.
• First angle projection is commonly used in Europe and Asia, where the object is imagined to be in the first quadrant of a Cartesian coordinate system.

• Third angle projection is commonly used in North America, where the object is imagined to be in the third quadrant of a Cartesian coordinate system.

Q2. Type of coardinet systm
Ans. 
There are various types of coordinate systems used in design engineering, such as Cartesian, polar, cylindrical, and spherical coordinates.
• Cartesian coordinate system uses x, y, and z axes to define a point in 3D space.

• Polar coordinate system uses radius and angle to define a point in 2D space.

• Cylindrical coordinate system uses radius, angle, and height to define a point in 3D space.

• Spherical coordinate system uses rad...read more

Q2. What is mean by relay and how it operates?
Ans. 
A relay is an electrically operated switch that uses an electromagnet to mechanically operate the switch contacts.
• Relays are used to control high power circuits with a low power signal.

• When the coil of the relay is energized, it creates a magnetic field that causes the switch contacts to close or open.

• Relays are commonly used in automotive applications, industrial controls, and home appliances.

• There are different types...read more
