select the best answer for the question.

1. which device makes use of pascals principle to turn a small amount of force into a large amount of force?

a. bourdon gages
b. archimedes screw
c. hydraulic press
d. barometer
mark for review (will be highlighted on the review page)

Explanation:

To solve this, we analyze each option:

• Option A: Bourdon gages measure pressure, not use Pascal's principle for force amplification.
• Option B: Archimedes screw is for fluid transfer, related to Archimedes' principle (buoyancy), not Pascal's.
• Option C: Hydraulic press uses Pascal's principle (\(F_1/A_1 = F_2/A_2\)), so a small force on a small area creates a large force on a large area.
• Option D: Barometer measures atmospheric pressure, not force amplification via Pascal's principle.

Answer:

C. Hydraulic press
