There is an experiment to determine the Young's Modulus of the wood which involves bending it.
The equation used to calculate it is like this
E=WX3/4ZDY3
Where D=amount of bending
W=force (N) which causes the bending
Z=width of the wood
Y=thickness of the wood
X=horizontal distance between the support
I am curious about the derivation of this equation.
Attempts:
Young's modulus = Stress/Strain
= (F/A)/(E/L)
F=W, A=YZ, L=X?, E=??
