Question

Race car teams will spend exorbitant money to gain even the slightest edge on their competition. At many oval race tracks, such teams even shift the location of the engine toward the inside of the turn in an effort to lower the moment of inertia of the race car with respect to an axis passing through the center of the curve. Such a car (known as a supermodified) is shown to the right. Notice the engine is placed between the left-side wheels. Obviously, this car is designed to turn only left. Suppose that the engine has a mass of 955 kg and is shifted in location 63.0 cm toward the inside of the curve. Assume that the engine is relatively small in comparison to the radius of curvature of the track and that the radius of the track turn is R = 27.5 m. Calculate the percent change in the moment of inertia of the engine about the center of curvature of the track caused by the shift in location.

Explanation / Answer

using error estimation % change = 2*0.63*100/27.5 = 4.58%
