Question

Race car teams will spend exorbitant money to gain even the slightest edge on their competition. At many oval race tracks, s 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 teams even shift the location of the Such a car (known as a supermodified) is shown to the t. Notice the engine is placed between the left-side s. Obviously, this car is designed to turn only left. Suppose that the engine has a mass of 1010 kg and is shifted in location 47.8 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 = 29.5 m. Calculate the absolute value of the percent change in the moment of inertia of about the center of curvature of the track chau sed by the shitino track Number

Explanation / Answer

Using error estimation % change = 2 x 0.478 x 100/ 29.5 = 3.24 %
