The force actually existing in eachportion of the mass is therefore the 21th part of what it was ineach portion of the added weight C, and will in this combinationdescend witli the 21th part of the velocity that it would do if itdescended freel), tliat is, the… … Fig. 2.- Plan. Suppose 900 feet in B, and 730 in A, represent the weights A,and B, balancing each other, and 170 the weight C, with a fallof 900 feet, the velocity acquired thereby when falling freelyis theoretically 240 feet per second; but 170 is the lOtith part of1800 (the sum of 900, 730, and…
