Hello all, I need to calculate the bending stress of a tapered cantilever beam. However, I would like to know how to calculate the moment of inertia. For a uniform shape beam, I know the Ix=(bh3)/12, but since h changes throughout the length of the beam how would inertia, I, be calculated? I was able to figure out the height of the beam as a function of x, H(x). Equation for H(x)= [(a-b)/L](x)+a where; a= height of beam at fix wall b= height of beam at end L= total length of beam x= point along length of beam. Any help would be greatly appreciated!!!
