Tapered Beam Deflection Coefficients
Tapered Beam Deflection Coefficients
(OP)
I have been working on a project where we need to check the deflection of a tapered beam and I have been looking up in Roark's "Formulas for Stress and Strain" Table 13a at the deflection coefficients for an end loaded cantilever beam look wrong or the table header has a typo as he has Inertia at Fixed End divided by Inertia at Free End of say 2 gives a deflection multiplier of 0.579 which would then reduce the deflection if you using the inertia at the fixed end to calculate the deflection, or am I wrong in this assumption and that to calculate the deflection of tapered beam you use the inertia at the free end in which case Roark's table would be correct.

However, since I'm far more proficient at SolidWorks / Cosmos than calculus, I'd take Cockroach's approach myself...
