I'm having some trouble understanding how to calculate the moment of inertia for a beam a certain X length that tapers at each end, and how to find the plastic and elastic section modulus after that. Would I have to set it up as a function that gives you the moment of inertia at any point as it...
I'm a bit confused with LRFD combinations. In the case of a machine like a big air compressor for example how could I apply load combinations? Would the dead load be the weight of the empty tank and would the live load be the air inside? Thanks for the help.
