Capgemini Interview Questions and Answers

Pumps are used to move fluids or gases from one place to another.

• Pumps are used in various industries such as water treatment, oil and gas, and manufacturing.

• They can be used to transfer liquids, create pressure, or circulate fluids.

• Examples include centrifugal pumps, diaphragm pumps, and vacuum pumps.

CNC works on a computer numerical control system.

• CNC machines are controlled by a computer program that dictates the movement and operation of the machine.

• The system uses numerical data to control the cutting tools and other machinery in the manufacturing process.

• Examples of CNC machines include milling machines, lathes, and laser cutters.

I am familiar with pumps through my experience managing inventory and equipment in previous roles.

• Managed inventory of pumps in previous job

• Coordinated maintenance and repairs for pumps

There are three types of lubrication for rotating mechanisms: hydrodynamic, boundary, and mixed.

• Hydrodynamic lubrication uses a fluid film to separate the surfaces and reduce friction.

• Boundary lubrication uses a layer of lubricant on the surface to reduce friction.

• Mixed lubrication is a combination of hydrodynamic and boundary lubrication.

• Examples of lubricants include oil, grease, and graphite.

• The choice of lubrication depends on factors such as speed, load, temperature, and...read more

Armature reaction refers to the effect of the magnetic field produced by the armature current on the main magnetic field of a DC motor.

• Armature reaction causes distortion in the main magnetic field of the DC motor

• It leads to a shift in the neutral plane of the motor

• Compensating windings are used to counteract the effects of armature reaction

• Armature reaction can affect the performance and efficiency of the motor

There are several types of bearings used in mechanical applications.

• There are four main types of bearings: ball bearings, roller bearings, plain bearings, and jewel bearings.

• Ball bearings are the most common type and are used in applications with low to moderate loads.

• Roller bearings are used in applications with heavier loads and higher speeds.

• Plain bearings are used in applications with high loads and low speeds.

• Jewel bearings are used in precision instruments and watches.

• O...read more
