ame upward at d. That is, the weight is supported bythe four forces; viz., P + 2P + 2aP + 23P = 15P.Hence W = 15P = (24 - 1)P, or, in general, W = (2* - i)P. The tension on the beam is equal to TT + P, or 24P. 224. The following are other forms of pulleys, forwhich the relations of P to PFcan be… … Fig. 166. Fig. 167. 225.
