Question

a motor speedway has turns with radii of 335.28 m that arebanked at 33 degrees what is the " no friction" speed for car on these turns? During NASCAR race cars go through turns at 320km/hr.
Do they need friction to take turns at this speed? Prove withcalculations a motor speedway has turns with radii of 335.28 m that arebanked at 33 degrees what is the " no friction" speed for car on these turns? During NASCAR race cars go through turns at 320km/hr.
Do they need friction to take turns at this speed? Prove withcalculations

Explanation / Answer

We have the formuula for angle of banking is                                 tan = v2/(rg) speed of the speed of the car is                  v = [rg tan] The coefficient of the static friction is               = v2/(rg) Here v =320 (5/18) m/s Substitute the values
