Answer» At the balancing condition, ANTICLOCK wise moment must be equal to clock wise moment. Clockwise moment, about the balancing point is = moment by 80 GF =80gf×(80−X)cm =6400gfcm−80Xgfcm.....(1) Anticlock wise moment about the balancing point is = moment by 10 gf + moment by 50 gf =10gf×(X−10)+50gf×(X−50) =10Xgfc,−100gfcm+50Xgfcm−2500gfcm.....(2) At the balancing condition, Clock wise at equilibrium = Anti clock wise moments. 6400−80X=100X−100+50X−2500 6400+2600=140X⇒140X=8000 ⇒X=1408000=64.28 Scale is BALANCED at 64.28 cm from the beginning. |
