Which type of actuator generates a good deal of power but tends to be messy? A. electric B. hydraulic C. pneumatic D. (B) and (C) above E. None of the above

electric
hydraulic
pneumatic
(B) and (C) above E. None of the above

The correct answer is D. (B) and (C) above.

Hydraulic and pneumatic actuators are both types of fluid power actuators. They generate a good deal of power, but they can be messy because they use fluids. Hydraulic actuators use oil, while pneumatic actuators use air.

Electric actuators are a type of non-fluid power actuator. They are not as messy as hydraulic or pneumatic actuators, but they do not generate as much power.

Here is a more detailed explanation of each option:

  • Option A: Electric actuators are powered by electricity. They are a type of non-fluid power actuator. They are not as messy as hydraulic or pneumatic actuators, but they do not generate as much power.
  • Option B: Hydraulic actuators are powered by hydraulic fluid. They are a type of fluid power actuator. They generate a good deal of power, but they can be messy because they use fluids.
  • Option C: Pneumatic actuators are powered by compressed air. They are a type of fluid power actuator. They generate a good deal of power, but they can be messy because they use fluids.
  • Option D: (B) and (C) above. This is the correct answer. Hydraulic and pneumatic actuators are both types of fluid power actuators. They generate a good deal of power, but they can be messy because they use fluids.
  • Option E: None of the above. This is the incorrect answer. Hydraulic and pneumatic actuators are both types of fluid power actuators. They generate a good deal of power, but they can be messy because they use fluids.
