Aramark Diploma Electrical Engineer Interview Questions and Answers

A basic hydraulic circuit diagram illustrates fluid power systems using components like pumps, valves, and actuators.

• Components include a hydraulic pump, which generates flow.

• A directional control valve directs fluid to the actuator.

• An actuator (cylinder or motor) converts hydraulic energy to mechanical work.

• Pressure relief valves protect the system from overpressure.

• Hydraulic fluid is typically oil, which transfers po

Key considerations for purchasing EOT crane ropes include material, load capacity, safety standards, and maintenance requirements.

• Material: Choose between steel wire ropes or synthetic ropes based on application; steel is durable, while synthetic is lightweight.

• Load Capacity: Ensure the rope can handle the maximum load of the crane; for example, a 10-ton crane requires a rope rated for at least 10 tons.

• Safety Standards...read more

EOT cranes can face various issues affecting performance, safety, and efficiency, requiring regular maintenance and troubleshooting.

• Electrical failures: Issues with the control panel or wiring can lead to operational failures.

• Mechanical wear: Components like gears and bearings may wear out, causing noise and reduced efficiency.

• Overloading: Exceeding the crane's load capacity can lead to structural damage or failure.

To make the red fishes 98%, 50 fishes have to be removed from the aquarium.

• Calculate 1% of 200 fishes, which is 2 fishes.

• To make the red fishes 98%, subtract 1% (2 fishes) from 99% (198 fishes).

• To find the number of fishes to be removed, divide the difference by 1% (2 fishes).

• Therefore, 50 fishes have to be removed to make the red fishes 98%.

To make the red fishes 98%, 50 fishes have to be removed from the aquarium.

• Calculate 1% of 200 fishes to find the number of red fishes.

• Subtract the number of red fishes from 200 to find the number of non-red fishes.

• Calculate 2% of the total number of fishes to find the desired number of red fishes.

• Subtract the desired number of red fishes from the current number of red fishes to find the number of fishes to be removed.
