compressive strength Definition and 15 Threads

Hello, Why is it more difficult to break a shorter bone that is cut into a cylinder than a longer cylindrical bone by pressing the bone vertically from its top despite sharing the same cross-sectional area?

Hello, Do all of aluminum bars (or load cells) made from the same type of aluminum (i.e high purity aluminum or different types of aluminum alloys) share the same exact compressive strength or are there variations in compressive strength even among the same type of aluminum like high purity...

Ok, i have been searching the google for about an hour and have come up dry. I am trying to either test at home or find some actual numbers for how much inner pressure a thin walled (3mm) cardboard tube take before it bursts? IE like filling it with water and then it pops. Second, im looking...

Hello, I'm an avid fan of science and math and love trying to solve the worlds problems using both. While I don't have any formal education in a science or math field I love using my natural talents in those areas whenever possible. I also love anything Science Fiction/Fact or Comedy related...

I have no formal training in any type of engineering, so if my request is confusing, I apologize. I believe I am seeking data on the ultimate internal stress of various silica aerogels in compression mode. I found a paper published by Dylan J. Boday where CVD of cyanoacrylates was used to...

I don't attempt solving a problem until I fully understand it, conceptually. After the hit (when maximum velocity is reached) the person starts losing momentum, having a constant upwards acceleration. The forces acting on the person are gravity and the normal to the ground. $$N - mg = ma$$...

A cloumn has a compressive strength of 220MPa, but its Euler yeild stress is 350MPa. its compressive strength is less than its euler stress. what does this mean?

Homework Statement Fracture load = 56000lb Radius=3 in Compressive strength = (F/pi*(r)^2) CS=630psi I was wondering if I did it right. Thanks

Hello everyone. I have a question about compressive strength of concrete. It is said that (in my country) 150 mm x 150 mm x 150 mm concrete cube is used for concrete testing. Someone asks me why 100 mm x 100 mm x 100 mm is not used. In fact, I know that sometimes it is allowed or even preferred...

Hi guys, Would like to know what's the highest compressive strength ever measured in any material, and what material that might be. Specifically wondering if there are any materials with gigapascal-level compressive strengths. Thanks! Rgds, Wally

Hi, as the compressive strength of concrete formula is max load applied/ surface area, could you say that the compressive strength of concrete is inversely proportional to it's surface area or this would make no sense as the concrete with a smaller surface would have a smaller max load anyway...

It's a really tricky one to work out, but does anyone have any suggestions of how to measure compressive strength? Thanks a lot.

in compressive tests of concrete blocks in a lab, there must be maximum contact between the press and the concrete, i am told that if you place a piece of waxed paper between the press and the concrete, or even if one of the surfaces is slightly wet, your results will be very distorted and even...

so here it is, I want to build a sphere with pressure being exerted uniformly on all sides. the sphere will be immersed in a fluid and have mass pumped out(to create buoyancy.) I have calculated the strength of the sphere to be... C=((Pw-Pi)r)/2T where Pw=Pressure of the Water Pi=Internal...

[b]1. State what is meant by the compressive strength of a material [b]3. The answer given in the mark scheme says - (compressive) stress/F/A/pressure AND to break/yield/shatter does anyone know what the answer to this question is? i don't really understand! thanks.
