A turn of radius 20m is banked for the vehicles going at a speed of 36 km/h. If the coefficient of static friction between the road and the tyre is 0.4, what are the possible speeds of a vehicle so that is neither slips down nor skids up?
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
Given, 
The road is banked with an angle,
When the car travels at max. speed so that it slips upward, 
acts downward as shown in Fig. 1
So, 
And 
Solving the equation we get,
So, the possible speeds are between 
and 
.
