Beam Dimensions: Length: 10 in. Width: 1 in. Thickness: 0.125 in. G Calculations: P 880190009 Figure 2: Dimensions of the aluminum beam. Derived Flexure Formula for Bending stress: f = Mc/l = 6PL/(bt^2) Where: M = bending moment at gage centerline, in-lbs (N-m) c = semi-thickness of beam, in (m) 1 = moment of inertia of beam cross-section, in^4 (m^4) P = load, lbf (N) L = effective beam length, in (m) b = beam width, in (m) t = beam thickness, in (m) Experimental Modulus of Elasticity = E= Af/Aε Percent Error = ((Published Value - Experimental Value)/ (Published Value)) x 100
