what exactly does one put in the lab report on that? what conclusions do i have to draw.\how do i structure my report to make it tidy and easy to read? also where does one find information to use in reference and literary review? a sample will be most useful.
Compression tests: Buckling and compression.?
I'm afraid your question is not worded too well - it's tricky to know what you're asking for.
I take it this is for school? If it is, it's probably best to ask your teacher to clarify what they're after. I'm sure they will be able to make it clear without you having to see a sample - it may make it difficult for you to reach your own conclusions if you see another report.
Reply:you might want to read up on youngs moduels of elasticity and maybe the different types of forces like tension, strain, shear ect the best way to see these is with a beam, search for bending moments of a beam
Reply:I completely agree with kpbunches on this question.
I'll try to help by suggesting that what you mean is when does a strut fail by compression and when by buckling? As I remember it (and it's from a very long time ago!) the criterion lies in the value of k/L for the strut. L is its length and k is the minimum 'radius of gyration' for its cross section. When k/L is very small the strut fails by buckling,(for which either the Euler or the Rankine-Gordon formula* gives the failing load). When k/L is large the failing load is, of course, given by S.A where S is the failing stress in compression and A is the cross-sectional area.
(* Euler for long struts, Rankine-Gordon for medium length)
