why modulus of rupture of concrete beam affected by size of specimen?

Answer 1

I would imagine that the eccentricity of the load implied would differ with beams of different cross sections.

For instance, a load placed on a 600ht x 300w beam would result in a compressive stress on the top surface of the beam at 300mm from its centreline, while an equal tensile stress would act on the bottom face at 300mm from centreline. A larger beam (say a 1200mm deep beam) would have the two opposing forces act at a larger eccentricity from the centreline (ie, 600mm either way).

Answer 2

the federactualy conpoment of a large doctorious dependes on the size of it uterious. there for crossing the yackot moverlous, to the left, in side from the middle, once moved , it creats a fat hunger feed, where all doglems boobgle on the jhermeys. once opened the feages hump the yaklots, leaving it with a jolaperious, so there for, yes modulus of rupture of concrete beam affected by size of specimen.

Answer 3

that's because the raptures of rupture are concentrating their beams of species towards your modules.... theres only one thing to do !!! FIGHT BACK !!!! GIVE THEM A TASTE OF THEIR OWN MEDICINE !!!!

Answer 4

Because concrete has no tensile strength,

Answer 5

The answer lies in the soil, search and dig it, ok innit
