Pascal's Principle Lab Idea for AP Physics BC

AI Thread Summary
A user seeks lab ideas for demonstrating Pascal's Principle (F2/A2 = F1/A1) for AP Physics BC, considering a hydraulic car lift model. Another participant shares a successful project using a 1L and 2L bottle setup with pistons, noting that varying weights can effectively demonstrate the principle. The discussion also touches on the ease of measuring force through the weight of the masses used. Additionally, there is curiosity about other applications of Pascal's Principle beyond piston systems. The conversation highlights practical experimentation and encourages exploring diverse applications of the principle.

hi, I'm new to this forum and i hope that you guys can help me with this and also in the future, i am currently taking ap physics bc.

i need an idea for a lab on pascal principle (F2/A2) = (F1/A1), i was thinking about replicating a hydraulic car lift, but how would you measure the force?

thanks

hmm... For my son's grade 5 project we used a 1L skinny plastic water bottle connected to a regular 2L pop bottle. We made pistons with the binary acrylic you can buy at most hobby shops. Then connected the two bottles at the bottom. Since the surface areas of the small bottle to the large one, when mostly filled with water and then the pistons were installed you pushed the little piston 3cm and the big one in the pop bottle went up 1 cm. Worked great.
 
One could use different masses on each 'piston'. This way the force would simply be the weight of each mass.
 
that sounds cool, i'll give it a try
does anyone know if there is any other application of pascal's principle besides those involving pistons-like objects?
btw what is binary acrylic?
 
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
