Kia Motors Diploma Trainee Engineer Interview Questions and Answers

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.

• Stress is a measure of the internal forces within a material, typically caused by external loads.

• Strain is the measure of the deformation or change in shape of a material in response to stress.

• Stress is usually represented by the formula: Stress = Force / Area

• Strain is typically represented by the formula: Strain = C...read more

Mechanics is the branch of physics that deals with the behavior of physical bodies when subjected to forces or displacements.

• Mechanics involves studying the motion of objects and the forces acting on them.

• There are two main branches of mechanics: classical mechanics and quantum mechanics.

• Classical mechanics deals with macroscopic objects and their motion, while quantum mechanics deals with microscopic particles.

• Example...read more

Moment of inertia is a measure of an object's resistance to changes in its rotation.

• Moment of inertia is the rotational analog of mass in linear motion.

• It depends on the mass distribution of an object and the axis of rotation.

• For example, a solid sphere has a higher moment of inertia than a hollow sphere of the same mass.

• Moment of inertia is often denoted by the symbol 'I' in equations.

Force is a physical quantity that can change the state of motion or shape of an object.

• Force is a vector quantity, meaning it has both magnitude and direction.

• It is measured in units of Newtons (N).

• There are different types of forces such as gravitational force, electromagnetic force, and frictional force.

• Force can cause an object to accelerate, decelerate, or change direction.

• Examples of forces include pushing a car,

CI engine stands for Compression Ignition engine, while SI engine stands for Spark Ignition engine.

• CI engine operates by compressing air to a high enough temperature to ignite the fuel without a spark plug

• SI engine uses a spark plug to ignite the fuel-air mixture

• Examples of CI engines include diesel engines, while examples of SI engines include gasoline engines

Front wheel drive is a type of vehicle transmission where power is sent to the front wheels for propulsion.

• In front wheel drive vehicles, the engine sends power to the front wheels, which are responsible for both steering and driving.

• Front wheel drive is commonly found in compact cars and smaller vehicles.

• This type of transmission typically offers better traction in slippery conditions compared to rear wheel drive.

• Exam...read more

Rear wheel drive is a type of vehicle drivetrain where power is sent to the rear wheels only.

• Power is transmitted from the engine to the rear wheels for propulsion

• Common in performance cars and trucks

• Provides better weight distribution and handling compared to front wheel drive

• Examples include BMW 3 Series, Ford Mustang, and Chevrolet Silverado
