Reaction Force On Ladder and Wall Case

AI Thread Summary
In the discussion about the reaction force on a ladder leaning against a wall, participants explore why there is no vertical reaction force at the wall. The scenario involves a uniform ladder of mass and length, positioned against a smooth vertical surface. The key point is that the wall exerts only a horizontal force due to its smoothness, while the ground provides the necessary vertical support. Additionally, it is noted that there may be other forces at play that are not accounted for in the initial analysis. Understanding these forces is crucial for solving the problem accurately.

because...

A uniform ladder of mass and length is leaned against a smooth vertical wall.

PS: In your problem there might be another force "missing" as well.

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...
