Web3 hours ago · Expert Answer. What is the maximum approximate vertical reaction in the structure under the load case shown? Select one: a. 1.4kN b. 1.6kN C. 1.1kN - d. 0.9kN× Assume that there is a point of contraflexure 0.8 m away from each external support and treat them as internal pins. Your answer is incorrect. WebDec 31, 2015 · Point of Contra flexure [Inflection point]: It is the point on the bending moment diagram where bending moment changes the sign from positive to negative or vice versa. It is also called Inflection point. At the point of inflection point or contra flexure the bending moment is zero. Relationship between load, shear force and bending momentFig.
