Renault-Nissan 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.

• In fi...read more

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

Q1. What is the relay
Ans. 
A relay is an electrically operated switch that uses an electromagnet to mechanically operate a switch.
• Relays are used to control high power circuits with low power signals

• They are commonly used in automotive, industrial, and household applications

• Relays can be classified based on their operation, such as electromechanical relays or solid-state relays

Q2. Ohm's law and current
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, given constant resistance.
• Ohm's law equation: V = I * R (voltage = current * resistance)

• Current is the flow of electric charge through a conductor

• Higher voltage leads to higher current flow, given constant resistance

• Lower resistance leads to higher current flow, given constant voltage

Q3. What is drawing first angle
Ans. 
First angle projection is a method of representing a 3D object on a 2D plane using a specific arrangement of views.
• First angle projection is commonly used in Europe and Asia.

• In first angle projection, the object is placed in the first quadrant of the coordinate system.

• The views of the object are projected onto the planes of projection from the object's perspective.

• The top view is projected onto the horizontal plane, th...read more
