Hello, I am doing a problem for work where I use a deflected beam as a model. Basically, I am using a beam with two fixed ends and a force directly in the middle. The deflection equation for this model is: delta_max=FL^3/(192EI) This assumes I is constant through the entire beam. However, how would I obtain delta_max if I is different to the left and right of the force (I_1 and I_2)? Thank you! P.S. Please see attached images for visuals.
