Completely solve and box the final answer. Please show the units to show the unit cancellations. Write legibly 10 Compute the indicated mean effective pressure in bar of a four-stroke 8” x 12” single acting Diesel engine with 8 cylinders that deliver 800 Bhp at 800 rpm. The engine consumes 80 pounds for every half hour of fuel with a heating value of 18,000 BTU/lb. Use a mechanical efficiency of 80%.
The horsepower (hp) that a shaft can safely transmit varies jointly with its speed (in revolutions per minute (rpm)) and the cube of the diameter. If the shaft of a certain material 2 inches in diamter can transmit 16 hp at 120 rpm, what must the diameter be in order to transmit 45 hp at 100 rpm? Round to 2 decimal places._______inches

The channel shape cross-section and the rectangular cross-section shown in the Figure Q4 are made of materials with elastic-perfectly plastic behaviour. The yield stress of the material used for the channel shape cross-section is σy = 449 MPa, whereas that used for the rectangular cross- section is 0.7%y. Compute the thickness of the web, t, of the channel shape section if the two cross sections have identical plastic bending moment about the z-axis.
