According to pascal's principle or pascal's law, the pressure at any point in a confined, incompressible fluid is transmitted all throughout the fluid such that the same change occurs everywhere.
00:14
In other words, at the same level or at the same depth from the surface of the fluid, the pressure is the same.
00:23
So, as a consequence of that statement, we can then relate the pressure.
00:31
Pressure at point one to the pressure at point two, at a certain point that if those points, two points are at the same level or at the same depth from the surface of the water.
00:42
So those pressures should be essentially the same.
00:46
And since pressure is defined as the ratio of force and area, then we would have f1 over area a1 must be equal to f2 over a2, where f is the pressure and a is the area.

In this problem, we're given with a small piston of hydraulic lift that has a radius of 6 cm.
01:06
So let's assign that as d1 or diameter 1 and a large piston with a radius of 25 centimeters.
01:14
So it's not corrected.
01:15
These are already radius, not diameters.
01:19
Let's use different rotations for these are...
