Currently there are seven I-Beam shapes available (from 27” to 96” depths) and 3 rectangular shapes (from 14” to 22”). In theory, this appears to be simple, but the equations can be complex, especially with distributed loads that are also a function of the location, x. A static load will be incremented at different locations along the beam to produce measurable strains. Hence the difference in results.
