What's the relation between chemical compositions and physical properties?

AI Thread Summary
The discussion centers on the relationship between chemical composition and physical properties of materials, questioning whether this relationship is one of equality or hierarchy. The focus is on a PhD project that aims to sort recycled materials based on chemical composition rather than traditional physical and mechanical properties. The participant is exploring the advantages of this new sorting criterion and its implications for material sorting. The conversation also touches on the distinction between academic work and PhD research. Overall, the dialogue emphasizes the need for innovative approaches in material sorting based on chemical composition.

Dear all, is the relation between chemical composition of a material and its physical properties a peering relation or a relation of subordination？

What are your thoughts on this? Is this for schoolwork?

nope, it's about my PhD project, we are now starting sorting of the recycled materials based on chemical composition, the traditional sorting criteria is mostly based on the physical and mechanical properties, I am thinking of the relation of this hierarchy, and wondering why is a new sorting criteria advantageous or specific over others.

Okay, I've got it now. PhD work has nothing to do with school. Check.

Can you post your outline for your PhD work?
 

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...
