"Pascal's law is a principle in fluid mechanics that states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions"
And Hydraulic Lift is an application of the Pascal's Law
A hydraulic lift is basically a force multiplier. It is used to lift heavy objects.
As shown in the video above a hydraulic lift is consist of two piston of different surface area Let a and A.
Let we apply a force f on smaller piston then
pressure on small piston is = f/a
Then
Pressure on Larger Piston = F/A
According to pascal's law
Pressure on smaller piston must be transferred to larger piston i.e.
Pressure on Smaller Piston = Pressure on Larger Piston
f/a = F/A
F = A*f/a as A > a so F > f Where A/a is known as multiplier factor
As in this Video a mass of 500g is able to support a mass of 3 kg. In the demostration each block is of 500g.
and one block is supporting six similar blocks. Have the look and share your views
I doubt the US would ever challenge the Russian ban on United States and European Union food imports as a violation of the World Trade Organization (WTO) agreements because the ban will likely hurt Russia more than the US.legal case management software
