What is the total piston displacement of a nine-cylinder engine with a bore of 5.5 inches and a stroke of 6 inches?

To determine the total piston displacement of a nine-cylinder engine, you need to calculate the displacement for a single cylinder and then multiply that by the number of cylinders in the engine.

First, the formula for the displacement of a single cylinder is:

[ \text{Displacement} = \frac{\pi}{4} \times \text{Bore}^2 \times \text{Stroke} ]

In this scenario, the bore is 5.5 inches and the stroke is 6 inches.

1. Calculate the area of the cylinder:

[ \text{Area} = \frac{\pi}{4} \times (5.5)^2 ]

[ = \frac{\pi}{4} \times 30.25 ]

[ \approx 23.76 \text{ square inches} ]

2. Now multiply this area by the stroke to find the displacement of one cylinder:

[ \text{Displacement of one cylinder} = 23.76 \times 6 ]

[ \approx 142.56 \text{ cubic inches} ]

3. To find the total displacement for all nine cylinders, multiply the displacement of one cylinder by nine
