The phenomenon of raising the outer edge of the curved road above the inner edge is to provide a necessary centripetal force to the vehicles to take a safer turn on the curved road is called Banking of Roads.
For the below figure
we can say that
The maximum angle with the vertical axis we can bend our cycle to avoid skidding on the road
is given by
where
V = velocity
r = radius of track
angle with which cycle leans
The maximum angular velocity of rotation of the platform, so that object will not skid on it.
Is given by
where
Angular velocity
r = radius
coefficient of friction
From the figure
we can say that
the maximum velocity by which vehicle can turn on a circular path of radius r
So that the vehicle does not skid away from the road is given by
where
Safe vector move
r = radius of the curve
coefficient of friction
From the figure
We can say that
The minimum angular velocity a biker should rotate in a circular motion on the wall of death well so that it does not fall down
will be given by
where
= minimum angular velocity
coefficient of friction
r = radius of Rotor
As shown in figure

Centripetal Force F acts on the body along the radius and towards the center.
And it is given by
where
F = Centripetal force
Angular velocity
n = frequency
Whether the chain remains on a table or slides down from the table will depend on the
Length of the l' part.
Let's try to understand this with the help of the following video.
Friction between the sliding surfaces of two objects can be reduced by making the surfaces in contact smooth by polishing them. Sliding friction between the moving parts of vehicles can be reduced by using oil, grease or graphite.
For the below figure
For the minimum value of P, its angle from the horizontal should be equal to the angle of friction.
I.e = angle of friction.
And the minimum value of P is given by
