Transcription: In this example, we're analyzing the mechanical advantage of a wheel and axle system. Now, according to the problem, the wheel has a diameter of 24 inches. On the other hand, the axle has a diameter of only 2 inches. And the question is, what's the mechanical advantage of this system? Well, we have an equation for the mechanical advantage of a wheel and axle system. Now remember, that equation is different than the equation for the mechanical advantage of a lever, so we have to use the proper equation. For this situation the proper equation is the mechanical advantage of a wheel and axle syste ...
