Renault Nissan Technology & Business Centre India Research and Development Interview Questions and Answers

Caster, camber, and toe are terms used in automotive engineering to describe the angles of a vehicle's wheels.

• Caster refers to the angle of the steering axis relative to vertical.

• Camber refers to the angle of the wheels relative to the road surface.

• Toe refers to the angle of the wheels relative to the centerline of the vehicle.

• These angles affect the handling, stability, and tire wear of a vehicle.

• For example, positive...read more

Auto alignment of steering is a process where the vehicle's wheels are adjusted to ensure they are pointing in the correct direction.

• Auto alignment helps to improve the handling and stability of the vehicle.

• It can also prevent uneven tire wear and improve fuel efficiency.

• There are three main types of alignment: front-end, thrust, and four-wheel.

• Alignment can be affected by hitting potholes, curbs, or other obstacles.

Basic manufacturing processes include casting, forging, machining, and welding.

• Casting involves pouring molten metal into a mold to create a specific shape.

• Forging involves shaping metal by applying pressure and heat.

• Machining involves using tools to remove material from a workpiece to create a desired shape.

• Welding involves joining two pieces of metal together using heat and pressure.

Suspension refers to the system of springs, shock absorbers, and linkages that connects a vehicle to its wheels.

• Dependent suspension

• Independent suspension

• MacPherson strut suspension

• Double wishbone suspension

• Multi-link suspension

Yes, I plan to pursue a PhD in my field of research.

• I have been researching potential PhD programs and have narrowed down my options.

• I plan to continue my research in the same field and contribute to the scientific community.

• I am also considering opportunities for teaching and mentorship.

• Examples of potential programs include XYZ University and ABC Institute.

Resistors are color-coded to indicate their resistance value.

• The first two bands indicate the significant digits of the resistance value.

• The third band indicates the multiplier.

• The fourth band indicates the tolerance.

• Black, brown, red, orange, yellow, green, blue, violet, gray, and white are the colors used.

• For example, a resistor with bands of brown, black, red, and gold would have a resistance value of 1.0 ohms with

The symbol of Mosfets is a combination of a rectangle and a triangle.

• The rectangle represents the body of the transistor

• The triangle represents the source and drain terminals

• The arrowhead on the triangle indicates the direction of current flow

Intensity of light refers to the amount of energy that is carried by light waves per unit area per unit time.

• Intensity is measured in units of watts per square meter (W/m²).

• It can be affected by factors such as distance from the source, absorption, and reflection.

• Examples of high intensity light sources include lasers and the sun.

• Low intensity light sources include candles and dimly lit rooms.
