    Moments Principle
AI Thread Summary
To determine force X using the principle of moments, the equation states that in equilibrium, the sum of anticlockwise moments equals the sum of clockwise moments. The discussion emphasizes the importance of selecting a point to take moments about, which is crucial for solving the problem. Participants suggest considering the placement of the third horizontal force in relation to existing forces. The user is encouraged to visualize the forces and their directions to better understand the equilibrium condition. Ultimately, understanding the correct application of the principle of moments is key to solving the problem effectively.

I am trying to determine force X

I know it is the principle of moments so I think you use this equarion - not sure though:

In equilibrium
(the sum of)anticlockwise moments = (the sum of) clockwise moments

however I am not sure how to do it?

thanks for any help!

Hi Jambob28! Welcome to PF! :wink:

Hint: you need to take moments about a point

the question asks you where the third horizontal force is

which point do you think you should take moments about? :smile:
 
Hi thanks for your help.

I am guessing the other arrow would be at the same level as arrow B but right instead of left?
So
B Y
<-----------|||||----------->

I really am pretty useless so I'm probably wrong.
 
hmm … look at the first diagram …

where is the third place where a force can be exerted? :smile:
 
well I guess you could pull it the other way?

so:
Y <-------------|||-----------> Pull

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...
