Hydraulic _____________ works on the principle of Pascal's law of transmission of fluid pressure?
Correct answer: A. Press
- A. Press
- B. Turbine
- C. Pump
- D. Coupling
Explanation
A hydraulic press uses Pascal's law: pressure applied to a confined fluid is transmitted throughout the fluid and produces a larger force on a larger piston. Turbines, pumps, and couplings use different operating principles.
