Finding the center of gravity & mass by torque?

AI Thread Summary
To find the center of gravity and mass of a meter stick pivoted at the 50-cm mark, weights of 150 g and 200 g are placed at the 10-cm and 75-cm marks, respectively, to balance it. When the weights are interchanged, the pivot point shifts to the 43-cm mark. This indicates that the center of gravity of the meter stick is not at its midpoint due to material inconsistencies. The problem requires calculating the mass of the stick and its center of gravity using torque principles. Further discussion on this topic can be found in the existing thread in Intro Physics.

I don't know how to do these kinds of problems; I just need an example of one, could someone just work it out with an explanation?
Feel free to change the values or whatever.
This particular problem isn't to turn in, I'm studying for a test on this material.

A meter stick is pivoted the 50-cm mark but does not balance because of nonconformities in material.
150 g and 200 g weights ar placed at the 10-cm and 75-cm marks to balance the meterstick.
When the weights are interchange, the pivot point is at the 43-cm mark.
find the mass of the stick and the center of gravity.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
