The crank-slider mechanism in figure 3 has crank
radius rag = 0.15 m and connecting rod length
Lgp = 0.30 m. The piston D is fixed in a trace against
horizontal motions. Crank AB runs at a constant
rotational speed nAB = 2000 rpm. The mechanism is
considered only at the instance where the crank
orientation is 6 = 60 deg.
