The elements of the mechanics of materials and of power transmission (1911)
King, William Richard, 1852- · New York, J. Wiley & sons; [etc., etc.] · leaf 45
whole load, is equal to W. It is evident that the support reactions are each — pounds. 2 To find the bending moment at any section a, distant x fromthe left support, we may assume the uniform load to be madeup of a number of parallel forces each equal to w. There are BENDING-MOMENT AND SHEAR… … Fig. 35. The bending moment at the section a is then ,, o K^^ ^Lx wx^Ma = Kix — wxX- = 2 2 2 — {L — X) = 2 2 That is, the bending moment at the section is proportional tothe product of the segments into which the section divides thebeam, and the bending-moment diagram is therefore a parabola,as…
