Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. Archimedes law
  2. Bernouli’s law
  3. Reynold’s law
  4. Pascal’s law

Correct answer and explanation

Correct answer: Pascal’s law

Explanation: ✅ Correct Answer: D) Pascal’s law 📚 Explanation: A hydraulic press works based on Pascal's Law, which states that any pressure applied to an enclosed, incompressible fluid is transmitted equally in all directions throughout the liquid. By applying a small force on a smaller piston, a significantly larger force can be generated on a larger piston due to the area difference. This mechanical advantage allows hydraulic systems to lift or crush heavy industrial loads easily.
