b are constants dependent upon the natureand construction of the rope, and JR, is the resistance tobe overcome, or the tension of the cord .4 C. The values ofa and b for different ropes have been ascertained by experi-ment, and tabulated. Finally, if the same rope be woundupon pulleys of different… … HURTFUL RESISTANCES. 137 a + bR In the case of the pulley, if we neglect friction, we shallhave, when the motion is uniform, P = R + a-±™, for the algebraic expression of the conditions of equilibrium.The yalues of a and b have been determined experi-mentally for all values of H and _Z), and…
