The engine of Prob. 14.3 uses a connecting rod 300 mm long. The masses are m3A = 0.80 kg, m3B = 0.38 kg, and m4 = 1.64 kg. Find all the bearing reactions and the crankshaft torque for one cylinder of the engine during the expansion stroke at a piston displacement of X = 30%

(ωt = 63.2◦). The pressure should be obtained from the indicator diagram, Fig. AP14.3 in Appendix B.
