The slider-crank mechanism of a single-cylinder diesel engine is shown in Fig. P17-2. A gas force P = 17 800 N acts to the left through piston pin C. The crank rotates counterclockwise at a constant speed of 1 800 r/min. Draw the mechanism to a scale of 1 mm = scale of 1 mm = 0.3 m/s, an acceleration scale of 1 mm = 22.5 m/s, and a force scale of 1 mm = 175 N. Make a combined static- and inertia-force analysis. (a) Determine the forces F14 and F12 and the torque T2 in newton-meters exerted by the crankshaft on the crank for equilibrium. (b) Determine the magnitude and direction of the shaking force and its location from point O2. 2 mm.
