The effect of rocker ratio and connecting rod length on the performance of a crank-rocker mechanism with an extended rocker input link

The effect of the rocker ratio, and the distance between the crank and rocker extreme positions, of a general four-bar mechanism with an extended rocker arm length are analyzed. The crankshaft rotation was set at a constant rate of 2000rev/min, and all mechanisms had the same strokes. A constant inp...
