Calculation of movement caused by a change in pressure

AI Thread Summary
The discussion revolves around calculating the movement of a closed cube connected to a high-pressure chamber when a small opening is created at the bottom. The cube is initially at 6 bar pressure while the surrounding room is at 1 bar. When the opening occurs, the pressure difference will create a force acting on the cube. The key equations mentioned are PV = constant and F = PA, but the user struggles to apply them effectively. Understanding the pressure differential and its impact on force and movement direction is crucial for solving the problem.

Homework Statement


Imagine you have an unflatable closed cube (z x z x z) which is connected to a chamber with a constant pressure of 6 bar (so the pressure in the box is also 6 bar). The box is hanging on a wire in a room in which the pressure is 1 bar. At t=0 a small part of the bottom of the cube opens (a x a x a , a < z). What is the force on the box and in what direction will it move?

Homework Equations


Sorry, but i have no idea. I tried using the standard PV = Cte and F=PA, but without any result so far

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...
