that the equivalenteffort Fe to be applied to the tool is 1,200 lb., and we requireto find the force Fc to be exerted at the crank-pin C. Inthis case Fc and F^ are both in the direction of their velo-cities, so that we have Pc = VeFe_ 1,200 X 0-95 = 1,140 lb. approx.

The instantaneous or virtual centre of any link or membera of a mechanism with relation to any link b is, as we haveseen already,* the point about which the first link a may beconsidered as rotating at any instant if…
