Hydraulic Lever: Effect of Force on Pressure

AI Thread Summary
Applying a force on a smaller piston in a hydraulic lever transmits pressure throughout the fluid, causing the larger piston to move upward simultaneously. The movement of the second piston does not affect the pressure of the liquid; pressure is determined by the force applied divided by the area of the piston. If different forces are applied to the two pistons, the resulting pressure in the liquid can be calculated as the sum of the pressures from both pistons. Thus, the overall pressure increase in the liquid is p1 + p2. This discussion clarifies the relationship between force, area, and pressure in hydraulic systems.

I have a doubt about hydraulic lever


if a force f1 is applied at piston of smaller area a1 then pressure is transmitted to every part of fluid

due to aplication of f1 smaller piston move down and piston at other end move up

does the moving up of second piston have any effect on pressure of liquid

No, the two pistons will move at the same time (or very nearly so), so that the pressure is given by force/area.
 
If we apply force f1 on one piston and f2 on another such that p1 > p2 and one piston moves down and one up
then what is increase in pressure of liquid


will it be p1 + p2 ??
 
Yes. It will it be p1 + p2.
 
thanks a lot
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
