It's not just how many cylinders a car has that's important but how much power each one can make as it pushes out its piston. That depends on the size of the cylinder, which, in turn, depends on two key measurements: the diameter of the cylinder (called its bore ) and how far the piston moves out (its stroke ). The area of a circle is π × radius 2 , and since the bore is twice the radius, the useful volume of a car cylinder is (π/4) × bore × bore × stroke. In physics terms, the volume of the cylinder is related to how much work the fuel does as it expands, how much energy it transfers to the piston, and (if we consider how often this happens), how much power the car makes. So the bore and stroke are very important—and that's why they're often quoted in technical specifications for car engines along with the number of cylinders. You'll often see these measurements written in the form bore × stroke (so, for example, 90 × 86mm means a bore of 90mm and a stroke of 86mm).
Similarly, the rear reactive force can be calculated at the forward contact point as:

The final key piece is the inverter. The current delivered by the battery is a direct current, but the motor, like your hairdryer, needs alternating current to operate. And that's exactly what the inverter does, turning direct current into alternating current.

3. Drag Force \(F_D\) : The force generated by the wind that slows the car down.
The Testing Process.
The CVPI came with many heavy-duty components, including a revised transmission and a beefed-up V8 engine. Both generations were powered by the iconic 4.6-liter "Modular" V8. Initially rated at 215 horsepower, the lump came with 235 horses on tap in 2001. Ford upgraded the mill to 239 horsepower in 2003 and 250 horses in 2004. The Crown Vic hit 60 mph in less than eight seconds and peaked at 129 mph (208 kph). Its top speed was electronically limited.
