Aside from the use of a meter stick (a fairly crude instrument), what significant source of error is inherent in the cantilever beam method for determining the elastic modulus?

Hint: the formula for the elastic modulus is: E= (4FL^3)/(δwb^3 ) where F = load, L = beam length, d = deflection, w = beam width and b = beam thickness.
