Point Rod Strings

AI Thread Summary

For the rod AB to be in equilibrium while suspended by strings OA and OB, it must hang vertically due to the gravitational force acting on it. The tension in the strings must balance the weight of the rod, ensuring that the net force is zero. This condition implies that the vectors representing the tensions in the strings and the weight of the rod are coplanar. Therefore, the plane formed by points O, A, and B must be vertical. The equilibrium condition confirms that the configuration of the strings and the rod maintains a vertical alignment.

A heavy rod AB is suspended from a point O by two strings OA and OB . Show that the plane OAB is vertical.

How to do this? Please help me.

Well, if nothing holds the rod AB except the strings, then, in order for it to be in equilibrium, it must hang. The rest is just vector algebra (3 coplanar vectors). The forces in the string together with the weight of the rod must cancel out.

Thread 'Light speed'

If light travels in a wave, couldn't we "speed it up" by making it travel in a straight line?

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
