Fresenius Medical Care Senior Engineer Interview Questions and Answers

Gears are mechanical components that transmit power and motion between rotating shafts. Two-stroke and four-stroke engines are types of internal combustion engines.

• Gears are used to change the speed, torque, and direction of power transmission.

• Two-stroke engines have a simpler design and are lighter than four-stroke engines.

• Four-stroke engines are more fuel-efficient and produce less pollution than two-stroke engines.

A latch machine is a digital circuit that stores data and can be used for memory and data storage applications.

• A latch machine is a type of flip-flop circuit that can store a single bit of data.

• It can be used for memory and data storage applications.

• It is commonly used in digital systems such as computers and microcontrollers.

• Examples of latch machines include D-latch, SR-latch, and JK-latch.

Laminar flow is smooth and orderly, while turbulent flow is chaotic and unpredictable.

• Laminar flow occurs at low velocities and is characterized by parallel layers of fluid moving in the same direction.

• Turbulent flow occurs at high velocities and is characterized by irregular fluctuations and mixing of fluid particles.

• Laminar flow is more energy-efficient and less noisy compared to turbulent flow.

• Examples: Laminar flow...read more

Generators work by converting mechanical energy into electrical energy through electromagnetic induction.

• Generators have a coil of wire that rotates within a magnetic field

• The rotation of the coil induces a current in the wire

• This current is then collected and transferred as electrical energy

• Examples include hydroelectric generators, wind turbines, and diesel generators
