AI Thread Summary
The discussion focuses on determining the force components acting on a swinging bar at a specific instant when it is pinned to a collar with horizontal acceleration. The bar has a uniform mass and is swinging with a clockwise angular velocity as it passes the vertical position. Participants are encouraged to analyze the forces at point A, considering both the acceleration of the collar and the angular motion of the bar. The conversation emphasizes the importance of applying relevant physics equations to solve the problem effectively. Understanding the dynamics at play is crucial for accurately calculating the forces involved.

Homework Statement



End of the uniform M-kg bar is pinned freely to the collar, which
has an acceleration a along the fixed horizontal shaft. If the bar has a
clockwise angular velocity w as it swings past the vertical, determine the
components of the force on the bar at A for this instant.

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...
