Arace car with a 106 inch wheelbase has its weight evenly distributed between front and rear axles. at 150 mph, on a race track with 1.0, the optimal brake force has 67.32% of the braking force on the front brakes. a new racing tire generates 1.2. at 150 mph, what percentage of the braking force should now be allocated to the front to achieve optimal braking?

Atmospheric air has a temperature (dry bulb) of 80° f and a wet bulb temperature of 60° f when the barometric pressure is 14.696 psia. determine the specific humidity, grains/lb dry air. a. 11.4 c. 55.8 d. 22.5 b. 44.1
