Mechanical Engineering Hydraulic Machines Difficulty: Easy
Choose an option
  • A
    Power absorbing machine
  • B
    Power developing machine
  • C
    Energy transfer (power transmitting) machine
  • D
    Energy generating machine

Answer

Correct Answer: Energy transfer (power transmitting) machine

Explanation

Concept

  • A hydraulic (fluid) coupling transfers torque hydrodynamically from input to output without changing the energy form; it does not create (develop) or primarily absorb power.

ThereforeIt is an energy transfer / power transmitting device.

Final AnswerEnergy transfer (power transmitting) machine.
