the small cylinder of a hydraulic press has an area of 2"(squared). If a force of 10# is applied to the small piston, how much is the pressure within the larger cylinder increased, according to pascal's principle.

Answer 1

is that, "force of 10 lbf"? if it is,
pressure is force per unit area, or:
P = F/A
P = 10 lbf/2 in^2
P = 5 psi (pounds per square inch)

so there,, :)
