Simple Conceptual Question Regarding Pascal's Principle

AI Thread Summary
Pascal's principle states that pressure applied to an enclosed fluid is transmitted undiminished throughout the fluid. The discussion revolves around the validity of a statement claiming that if pressure increases by a certain amount at one end of an oil-filled tube, the force at all points in the tube also increases by that same amount. Participants express confusion over whether the force can be considered uniform throughout the tube, given that force is dependent on both pressure and area. The distinction between pressure and force is emphasized, suggesting that while pressure may be uniform, force can vary based on the cross-sectional area. Ultimately, the statement's accuracy is questioned, prompting a deeper understanding of Pascal's principle and its implications.

Homework Statement


There's a conceptual question I've encountered in my reading, wherein we're supposed to determine the validity of a statement: "According to Pascal’s principle, if you increase the pressure enough so that the force at one end of an oil-filled tube increases by 10 N, the force will increase at all points in the tube by 10 N". The thing that's really bothering me is that this statement is supposedly true.

P=F/A

The Attempt at a Solution


I know that Pascal's principle pertains to the applied pressure at any point within an enclosed fluid; the applied pressure is transmitted undiminished, throughout. It isn't necessarily true to say the force is the same, is it? As such, I find the statement to be highly problematic.
Or, does the fact that it's an oil-filled "tube" imply that the area is uniform throughout. Even then, is it correct to say the force increases at all points by 10N?

Many thanks! :oldsmile:

If you assume, instead, that this statement is not true, does that resolve your doubts? That is, does assuming the statement not to be true line up with what you understand to be Pascal's Principle? Is pressure the same as force?
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
