How To Calculate the Deflection of a Parallel Chord Truss

[@sagarsa3805]

This is a good shortcut. But the only drawback is it only considers bending deflection. If we are considering vierendeel girders then we should also do shear deflection besides bending since shear stiffness of vierendeel girders are much less than that of diagonal truss.
