 Sci Advisor P: 5,095 How are you defining efficiency? "Efficiency" by itself is an ambiguous word. You need to be specific. Yes. There are standard well defined equations for all types of beams with varying loading and boundary conditions. In pure bending, they all stem from the solutions derived from the differential equation relating moment to shear: $$EI\left[\frac{d^4v}{dx^4}\right]=-W_{(x)}$$ Theory: http://www.efunda.com/formulae/solid...ams/theory.cfm http://en.wikipedia.org/wiki/Euler-B..._beam_equation Solved Equations: https://ecourses.ou.edu/cgi-bin/eboo...appendix=beams
