Magnitude and direction question

AI Thread Summary
To determine the magnitudes and directions of the forces exerted by the chain and bracket supporting a 495N sign, it's essential to analyze the forces involved using trigonometric functions. The discussion suggests using the law of sines or cosines, depending on the angles present in the problem. Participants emphasize the need for a clear description of the setup to provide accurate guidance. Understanding the constraints, such as the horizontal rod's inability to support vertical forces, is crucial for solving the problem. A detailed illustration or description of the angles and configuration would greatly assist in setting up the calculations.

"A sign weighting 495N is supported as shown in the attachment. Determine the magnitudes and directions of the forces exerted by the chain and by the bracket. assume that the horizontal rod cannot support vertical forces."


How do I set up this question? Do I use the law of Sins? Cos?

I really hate learning from the book, and since the book didn't show an example of this type of problem I don't really know where to start. Not asking for the solution, just a little kick start help. Thanks

cant see the jpg but if the angle is mentoined then you could use sins and cosines and then do the rest...
 
Describe the illustration in a little more detail

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...
