Not being a mechanical engineer, I was looking at simple beam deflection calculations in the machinery handbook and was wondering why there seems to be a discrepancy from posted formula on various sites.
For instance, for a beam with a single support and uniform load, the handbook states for maximum deflection:
ymax (at end) = (wl^3)/(8EI)
the formula ymax = -(w * l^4) / (8 * E * I) at x = l
from
So I guess the question is l^3 vs l^4 unless E or I are calculated differently in the handbook??
thanks.
