The 1.9-in.-diameter drive shaft AB on the helicopter in (Figure 1) is subjected to an axial tension of 10 000 lb and a torque of 295 lb · ft. Figure > 1 of 1

Diogram height, cm The bore diameter of each cylinder in a six-cylinder four-stroke petrol engine is 25 mm and the stroke length for each cylinder piston is 275 mm. During engine testing, the engine runs at 4250 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 7.85 cm2 and diagram length of 3.25 cm. For a pressure scale set at 525 kN/m2 per cm on the indicator diagram, calculate the indicated power developed by the engine. Give your answer in kilowatts (kW) to 2 decimal places.

Calculate the rate of flow of waste thermal energy out of the engine in the exhaust gases in kW (to 1 decimal point). If the air inlet temperature is 35 °C, the air to fuel ratio is 10:1, the inlet air mass flow rate is 37 kg/hr, the specific heat capacity of exhaust gas is 1.13 kJ/kg/K, and the exhaust temperature is 500 °C.
