An engineer wants to design an oval racetrack such that 3.20×10 3  lb racecars can round the exactly 1000 ft radius turns at 97 mi/h...?

 

An engineer wants to design an oval racetrack such that 3.20×10 3  lb racecars can round the exactly 1000 ft turns at 97 mi/h without the aid of friction. She estimates that the cars will round the turns at a maximum of 175 mi/h.  

  

Find the banking angle 𝜃 necessary for the race cars to navigate the turns at 97 mi/h  without the aid of friction. 

𝜃=

 

This banking and radius are very close to the actual turn data at Daytona International Speedway, where 3.20×10 3  lb  stock cars travel around the turns at about 175 mi/h.  

What additional radial force is necessary to prevent a race car from drifting on the curve at 175 mi/h?  

 

radial force =  ___________ N
