ll weight, p, is placed in Pv the equilibrium isfor the moment disturbed. The pointer swings and pres-ently comes to rest in a new position. The condition ofthings is then illustrated by Fig. 62. The point C, at which we may regard the weight of thebeam, etc., concentrated, now hangs to the left of… … which we regard as applied at C is negative. The momentof p with respect to 0 is positive. The moment of C in-creases when the index swings farther from its first position;the moment of p decreases at the same time. So, at acertain position of the index the two become equal andthere is equilibrium.…
