Angular momentum of a half filled waterbottle....

AI Thread Summary
The discussion centers on the angular momentum of a half-filled water bottle when it starts spinning. Participants emphasize the need for clarity regarding the axis of rotation, noting that the center of the bottle is not a defined axis. The conversation highlights the importance of specifying details in questions to facilitate accurate answers. The relationship between the bottle's angular momentum and its initial state is questioned, prompting further exploration of the factors involved. Overall, understanding the specifics is crucial for addressing the query effectively.

when compared to the angular momentum of the bottle at instant when it started spinning.
 
Spinning around what axis?

about its center.
 
The center is not an axis. The axis is a line. It may go through the center. But there are many lines going through a point.
Look, you need all the details of a question before you can even think about an answer. You cannot expect people to read your mind and figure out by themselves what you want to ask.
 

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...
