Webb28. Number of points of contra flexure for a double over hanging beam. a) 3 b) 2 c) 4 d) Infinite Answer: b Explanation: Point of contraflexure in a beam is a point at which bending moment changes its sign from positive to negative and vice versa. In the case of overhanging beam, there will be two points of contraflexure. 29. WebbSolution: Consider a section (X – X’) at a distance x from end C of the beam. To draw the shear force diagram and bending moment diagram we need RA and RB. Fig. 19.3 simply supported beam carrying -UDL. By taking moment of all the forces about point A. RB × 3 – w/2 × (4)2 = 0. RB = 1 × (4)2 / 2 × 3 = 8/3 kN.
