Pressure from a fluid on a solid piece of metal

AI Thread Summary
The discussion centers on the effects of extreme pressure on solid metal objects, particularly in the context of underwater environments. It highlights that while hollow objects like submarines are designed to withstand high pressures, dense solids like steel experience minimal observable compression under ocean pressures. The pressure at the bottom of the Mariana Trench is approximately 1.1 MPa, which is significantly lower than the 20-30 GPa pressures that can cause substantial compression in metals, typically achieved through explosive means. The dominant effect of high pressure on dense solids is an increase in temperature rather than physical deformation. Overall, the conversation emphasizes the resilience of solid metals under extreme pressure conditions.

I'm curious if anyone knows of a good video of an extreme amount of pressure being applied to a sold amount of metal or other dense object. We're learning about fluids in my class, and naturally we discussed submarines, empty bottles, etc. but everything mentioned seemed to be hollow on the inside. Such that as you go deeper you can see that the object will compress and eventually fracture I suppose. Of course I have no means to conduct the experiment myself, but I'm curious what would happen to an solid object that is also very dense.

Under ocean pressures, do not expect observable compression of a dense solid like steel ... you can get much higher pressures, but the dominant effect would be to make the steel hot.

... 20-30GPa pressure can get compressions up to 25% (usually using explosives)...[1]
By comparison, the water pressure at the bottom of the mariana trench is roughly 1.1MPa or 0.0011GPa. [2]

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...
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...
