A curve of radius 67 m is banked for a design speed of 95 km/h. If the coefficient of
static friction is 0.30 (wet pavement), at what range of speeds can a car safely handle the
I drew this freebody diagram.
The Attempt at a Solution
I have no clue how to do this.
Anyways, on the range of speeds there is a minimum speed and a maximum speed.
For the minimum speed friction has act enough that the car doesn't slip off the hill? I think, again I have no ****ing clue.
For the maximum speed friction has to be enough so the car doesnt fly off the curve. I think
Anyways we probably have to solve for some angle, but I have no clue where or how this happens.
Fnet is not existant here?
anyways, All I have done is convert 95kmh to m/s which is 26.388m/s.
SO nobody knows how to solve this question? It is ranked as one of the world's hardest problems.
