During the experiment the student will observe that thelever AB will balance in any position, so naturally the momentsround the centre F will always equalise each other. Example.—A weight… … W X ^ = P XJ 16 X i5 = P X 7 -r, 16 X 15 o ,v P = ^ = 3428 lb. Example.—A weight of 23 lb. is hung 6J in. from the fulcrum F inFig. 138. What will be the indications on a spring P whichsupports the arm 15 in. from F? As in the previous ex-amples we have W X jc = P y.y23 X 6o = Px 152.3 x6|- P = 15…
