Determine Reactions Fx = 0 i.e. Ax = Bx MB = 0 i.e. 0.3 Ay + 780 x 0.3 = 0; Ay = - 780 N = 780 N Fy = 0 i.e. - Ay - 780 = By; i.e. - - 780 N - 780 N = By ie. By = 0

Unformatted text preview: They are classified as to how they are supported. See page 345 for types of supports of beams. Shear and Bending Moment in a Beam Contd. The design of a beam requires the determination of the variation of the internal shear force, V and bending moment M acting at each point along the axis of the beam. Example Sketch the shear force and the bending moment diagrams for the beam shown below. Determine the maximum bending moment. Solution Solve in Class...
