In a 3-point bending test, a beam is loaded to a maximum force Fmax and then unloaded. The resulting deformations are reversible. The deflection occurring at Fmax depends on which material parameter:
1) Flexural strength
2) Compressive strength
3) EModul
4) Hardness
5) 0.2% proof stress
Only one answer can be correct. I'm torn between 2 and 3. Which makes more sense?

Loading...Where does the energy from a storage power plant come from? I can't seem to find anything about it online. I have to do a presentation on this, and my teacher said it has something to do with the sun. Can someone explain it to me more?
I saw on the internet that the ZR means it can go over 240 and if you want more, you should look for one with Y. But I have both, can I now drive 240 or more? Do I only need the Y or the Y in addition to the ZR?
First of all, my question is about easily understandable literature on this subject, i.e. a kind of textbook that systematically conveys the various topics. Furthermore, websites would also be helpful. Thanks in advance for your tips!
Good day, I have a question about a physics problem… the problem is: An empty wagon with a mass of 30 tons is moving at a speed of 30 km/h. It now begins to rain, and a total of 1500 liters of rain enters the wagon. The speed of the wagon after the rain is…
If the universe expands from within, as we are taught by the balloon, and since the balloon has walls and bursts due to too much internal pressure, I wonder if infinity and expansion can be explained more clearly.
(It was a question that came to me out of boredom, so please don't judge) Is it somehow possible to generate 60,000 bar of pressure to turn carbon into diamond?
Reversibly implies that it is a deformation in the elastic region, the modulus of elasticity describes the slope of the linear elastic region, i.e. how far the deformation takes place, how much force.
So should be right here.
The 0.2 % stretch limit tells you how the name already says to where sihc stretches the part from when it is permanently deformed. So it’s not important here, the rest has to do with the case nix.
The two strengths (1&2) indicate when it comes to breakage. So this is irrelevant.
The hardness (4) indicates the deformation under local pressure, i.e. not.
The yield point (5) indicates until where the deformation remains elastic (reversible), which is the case here.
Only remains the modulus of elasticity (3), which coincides with the relationship between stress and deformation 😉
Answer 3), I think E-module is correct.
I’d rather have said a thrust module, but they’re kind of stuck together.
But thrust refers to shear, not bending.
