A hydraulic press for compacting powdered samples has a large cylinder which is x = 11.8 cm in diameter, and a small cylinder with a diameter of y = 1.96 cm (see figure).
A lever is attached to the small cylinder as shown. The sample which is placed on the large cylinder, has an area of 4.09 cm2. What is the pressure on the sample if F = 319 N is applied to the lever?
I have no idea how to start and solve this problem. Thanks for the help!© BrainMass Inc. brainmass.com March 4, 2021, 6:19 pm ad1c9bdddf
This question involves torque as well as the Pascal's Principle (pressure applied to a confined fluid increases the pressure throughout by the same amount).
This solution is provided in 124 words. It discusses torque and Pascal's Principle in order to calculate force and pressure.
