In an automobile engine, the bore of a cylinder is its diameter, and the stroke of a cylinder is the height swept by the piston. Find the swept volume of a cylinder with a bore of 367 In. and a stroke of 4.50 in.

To find the swept volume of a cylinder, you can use the formula: \[ \text{Swept Volume} = \pi \times \left(\frac{\text{Bore}}{2}\right)^2 \times \text{Stroke} \] Plugging in your values: Bore = 367 in., Stroke = 4.5 in. So, \[ \text{Swept Volume} = \pi \times \left(\frac{367}{2}\right)^2 \times 4.5 \] \[ = \pi \times (183.5)^2 \times 4.5 \] \[ = \pi \times 33682.25 \times 4.5 \] \[ \approx 150747.58 \text{ cubic inches} \] This is the volume swept by the piston in one full stroke! Now, when it comes to engine performance, this swept volume—or as it's often called, “displacement”—is a critical factor. It gives you a peek into the engine's capacity, affecting horsepower and torque output. Larger displacement usually means more power, but it also leads to higher fuel consumption. So, in the engineering world, it's a balancing act between performance and efficiency! Additionally, a common mistake in calculating swept volume is forgetting to convert units to a consistent measurement system. If you’re working with different units (like metric vs. imperial), this could throw off your volume calculations significantly! Always make sure your units match to avoid the dreaded math mishaps!
