For example, here's the bending moment of a cantilever beam with a linear load which generates a point of contraflexure and a point of inflection (notice that to the left of the point, the curve has negative curvature, and to …

Witryna14 lis 2014 · Solution. In order to find point of zero shear. First find reactions towards beam because of load acting on it. For calculation of reaction R1, consider sum of moments at point D is equal to zero. i.e; R1 x 9 = (3×2) + (2×5) + (1×7) (7/2 +2) R1x9 = 54.5. R1 = 6.056T. Now for calculation of reaction R2.
