With the head of the moving load at L: R = 37.98 tons.Fig. 3 is the complete diagram. (CD) … Fig. 3. The truss is first supposed to be divided through BC, CL^and LK\ then, through CD, CK, and LK. {LK) = {R X 30 — 2 X 21,72 X 12) ^- 11.7 = 52.8 tons. The shear is, -S = 37-98 - 43-44 = - 546 tons. lOO NON-CONTINUOUS TRUSSES IN GENERAL. The diagram gives: {LC) — + 20.0 tons. {CK) 0.60 tons.…
