Figure 1.1 shows a gas engine coupled to a compressor; the two cylinders being horizontally opposed with pistons connected to a common crank pin. The stroke of each piston is 500 mm. The connecting rod length is 1.25 m. When the crank has turned through 60° from the inner dead centre on the firing stroke, the gas pressure in the engine cylinder is 1 MPa and the pressure in the compressor cylinder is 100 kPa. The speed of the crank is 200 rev/min. Calculate: 1.1. The net force on the engine and compressor piston. 1.2. The net torque on the crank.
