Hyundai Glovis Neem Trainee Interview Questions and Answers

Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.

• Capillary action occurs due to the combination of adhesive forces between the liquid and the surface it is in contact with, and cohesive forces between the liquid molecules.

• Surface tension is the tendency of a liquid surface to minimize its surface area, caused by the co...read more

Sensors and actuators are essential components in engineering. Pneumatics is a branch of engineering that deals with gas or air-powered systems.

• Sensors are devices that detect and measure physical properties such as temperature, pressure, and light. Examples include thermocouples, pressure sensors, and photoelectric sensors.

• Actuators are devices that convert energy into motion. Examples include motors, solenoids, and h...read more

Gears are mechanical components that transmit power and motion between rotating shafts. There are various types of gears and gear trains used in different applications.

• Types of gears include spur, helical, bevel, worm, rack and pinion, and planetary gears.

• Gear trains are used to transmit power and motion between two or more gears. Examples include simple, compound, reverted, epicyclic, and differential gear trains.

• A ge...read more

Crowning of pulleys is the process of shaping the pulley's surface to a slight convex curve. Belt drives have advantages over gear drives.

• Crowning of pulleys helps in maintaining proper belt alignment and prevents belt slippage.

• It also helps in distributing the load evenly across the belt.

• Belt drives are quieter, smoother, and require less maintenance than gear drives.

• They also allow for more flexibility in terms of di...read more

Questions related to stress-strain curve, modulus, elasticity, strain, hardness, and toughness.

• Stress-strain curve shows the relationship between stress and strain in a material.

• Young's modulus measures the stiffness of a material under tension or compression.

• Bulk modulus measures the resistance of a material to uniform compression.

• Elasticity is the ability of a material to return to its original shape after deformatio...read more

Work is the amount of energy transferred when a force is applied over a distance. Power is the rate at which work is done.

• Work is the product of force and distance

• Power is the rate at which work is done

• Energy is the capacity to do work

• Weight is the force exerted on an object due to gravity

• Mass is the amount of matter in an object

• Unit of weight is Newtons (N)

Gear manufacturing processes include honing, lapping, etc. Annealing, tempering, and quenching are heat treatment processes.

• Honing and lapping are finishing processes used to improve the surface finish of gears.

• Annealing is a heat treatment process that involves heating the metal to a specific temperature and then cooling it slowly to make it softer and more ductile.

• Tempering is a heat treatment process that involves h...read more
