NUR AFIQAH IZZATI BINTI OTHMAN Attorney PLATES ~ A N D Ill. hinge of all the forces acting on either side of the hinge can set up the required equation. Motor-car Principles | Project Gutenberg In case of beams supporting uniformly distributed load, the maximum bending moment increases with the square of the span and hence they become uneconomical for long span structures. If 'L' is the span of a three hinged arch, 'h' is the rise and 'W' is the u.d.l per unit length over the entire span, the horizontal reaction at each support is given by: Q2.
