Which ones of the following uses Pascal's principle A automotive hydrolic jack B trains' hydrolic brakes C a dish washer machine D a Bramah Press E a clothes washer F a street cleaning machine?

Answer 1

Pascal s law or Pascal s principle states that "a change in the pressure of an enclosed incompressible fluid is conveyed undiminished to every part of the fluid and to the surfaces of its container."--- wiki

Pascal s law was developed by French mathematician Blaise Pascal. The principle states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container. (see engineering.com)

The three that jump out as correct are A automotive hydrolic jack, B trains' hydrolic brakes and

D a Bramah Press.

The others use fluid (water) but I'm not sure they exactly fit Pascal's principle.
