Pendulum rotating about an axis

AI Thread Summary
The discussion centers on the analysis of forces acting on a pendulum rotating about the z-axis. There is confusion regarding the correct application of equations for balancing forces, particularly in the resolution of forces into components. It is emphasized that while forces can be decomposed into orthogonal components, they should not be treated as additive beyond their original form. Clarity in identifying actual forces and specifying the direction of analysis for each equation is recommended. The need for a precise problem statement is highlighted to facilitate further assistance.

I think you are marking too many forces on your diagram.
When you resolve a force into components, you are saying those components are equivalent to that original force. They don't add to it.
You can replace a force by two orthogonal components, but you can't keep taking more bits in other directions.

Identify clearly the actual forces, then in your calculations, use their components to produce balanced equations.
It might even help to say for each equation, what direction you are looking at.
 
I would love to help with this problem, but I have no idea what question you're trying to answer. What is the exact problem statement?

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
