How do I find the pressure capacity of a tungsten tube?

AI Thread Summary
To determine the pressure capacity of a tungsten tube, one must consider the material's tensile strength and Young's Modulus, comparing it to stainless steel. The wall thickness and radius of the tube are crucial factors, as they influence the pressure resistance. While tensile strength provides a general idea, it does not directly correlate to the gas pressure that causes failure, as the relationship varies with the container's shape. The distribution of tension within the tube is also not uniform, which can affect performance under pressure. Understanding these factors is essential for accurately assessing the pressure capacity of tungsten tubes.

I am looking to find the maximum psi or atm capacity of a tungsten tube of 99.9% tungsten. How would I do this?
 
Physics news on Phys.org
how thick are the walls of the tube? And what is the radius of the tube?
 
I don't have a particular dimension of tube yet. I am more concerned with the general pressure resistance properties of tungsten as a material; I haven't been able to find much on how much pressure it can take when compared to a stainless steel tube of the same width/radius. Any ideas?
 
Look up Young's Modulus or Elastic Modulus (same thing) for both materials.
 
You can get a general idea regarding the relative resistance of the materials by comparing the tensile strength.
Here is a table that shows both steel and tungsten.

However is just a very general idea. The distribution of the tensions in the is not uniform and the difference in elasticities may play a role too.
Besides, the tensile strength is not the pressure of the gas which will produce the breaking. The exact relationship between the pressure of the gas and the tension in the expanding walls depends on the shape of the container.
 

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'

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...
