Why is the pressure of fluid important for vapor pressure and cavitation?
Okay seems like I understand more. 1. But few question rises. If the vapor pressure will be going infiniti high we will receive large bubbles that can't explode? 2. What is going on in case of the open situation ( I mean the container without lid). We have this atmospheric pressure that... -

Why is the pressure of fluid important for vapor pressure and cavitation?
I know that. But I don't understand why it can be possible. What mechanism step by step is responsible for that. Why we talking even about vapor pressure inside the liquid. In most book it's write that vapor pressure is the pressure exert on the surface of the liquid. -

Why is the pressure of fluid important for vapor pressure and cavitation?
Okay, They other question why it need to be low to do it? It should be high to push with more energy the liquid? And also why we have vapor pressure in water? (vapor is not liquid and it confused me ) -

Why is the pressure of fluid important for vapor pressure and cavitation?
Everything you mentioned above is correct and I know that. But still don't understand your previous post: Here you wrote vapor pressure of the liquid...The vapor pressure of a pure substance is defined as the pressure exerted by its vapor in phase equilibrium with its liquid at a given... -

Why is the pressure of fluid important for vapor pressure and cavitation?
I can't understand that. First of all, what pressure of inside point? And then you mention vapor pressure of liquid (it's not a pressure of liquid but the pressure exert by vapor on surface of liquid. So we have two pressure of the same substance state? Secondary why the pressure vapor can... -

Why is the pressure of fluid important for vapor pressure and cavitation?
I straggle with getting full grasp of concept for Cavitation. I was finding statement that : If The pressure of fluid is lower or equal to the Vapor Pressure then it will start to boiling. And I can't understood the reason behind this. Why actually it happens? I understood where we came to the... -

Simplification of load on beam for Max M and D
Guys I have tricky question : I have beam loaded like that: Is there any easy way to do simplification of this load ( I don't mean transfer the UDL to Point Load). Mentioned that I mean the way to not do the calculation of moment to find max in 4 section and the two almost 4 double integrals...- Lisciu

Forces in symmetrical construction
Thanks haruspex, for your introduction. The problem i Getting here is that I'm not sure if I can do things like that : 1 . Find C.O.G. for UDL. Attached there Point Force. (if the UDL working on Width= 300 mm and Length 400 mm. I just multiply by 300 mm to get the distributed force on member...- Lisciu

Forces in symmetrical construction
Homework Statement We have a slab with uniform distrubuted load on it W. All dimensions. [/B] I'm looking for the force on the bolts and force on the hook contact surface. The Attempt at a Solution My way to do it is to reduce the problem for 2D. But the problem is that I'm not sure how to...- Lisciu

Directions of Friction Force (Pipe)
Okay now I Get it :) The main problem I have was to imagine this case. I don't even see it as simple and do some mistakes with assumption. Thank you haruspex now I see why you're a Gold member!- Lisciu

Directions of Friction Force (Pipe)
Because the wheel can't rotate in two direction at once. I mentioned that before. So friction work opposite to motion.- Lisciu

Directions of Friction Force (Pipe)
I do so many reps with this test and I conlude that in your way for it i can only observe rotation in antyclockwise in on finger and on other no slipping (in the finger that have more weight on it). But it's still tell that the force of friction are in the same clockwise direction...- Lisciu

Directions of Friction Force (Pipe)
You probably don't believe but it's actually act like I said :D it's rotate anticlockwise. So friction looks like acting clockwise in both points... Still don't get it. But I do other test easier. I take this cylinder between two fingers in position like you said Step 1 : Fixed left finger...- Lisciu

Directions of Friction Force (Pipe)
Heh, okay. But then again I can't imagine this case. How symmetrical thing like pipe can just on slip at B and not at A point. If some portion of the circle will move then it need to move on other side, because without that we need to asume that circle will compress or deform whatever... And to...- Lisciu

Undergrad Understanding Friction Direction in Static Problems
Okay. So there is 2 things that bother me. First one is the friction product of 3rd Newton Law? Consider that I push the ground with my leg to move mny body right. I exert force on the ground by push my foot to left. The ground exert force to push my leg. Is this pushing force from ground...
