Hey everybody,
My friend Brian and i are trying to understand the procedures for this specific test, has anyone here worked with this before?
Anyway, we are not sure when the wood beam should be considered broken. The test doesn't seem clear.
A simple outline of this test is a simply supported beam with 2 concentrated loads in order to induce the pure bending condition. The idea is to find the rupture bending stress.
We know the max deflection of this beam can be calculated from Mechanics of Material. Most of the variables in the equation are known for us, except for the modulus of elasticity. How should we approach this problem?. Brian told me he had the beams made from a wood supplier, maybe we could get the specs? or use tables according to the tree specimen? and if such which tables?
Thanks in advance.
