Vehicle turning on unbanked curve | Maximum velocity around an unbanked curve | Derivation of v(max)= sqrt(μrg)

 In this video we discuss - Vehicle turning on a horizontal circular track. We understand how friction of the road contributes to the centripetal force.

We also derive the equation - v(max)= sqrt(μrg).

Basically we answer the below questions:

 *When a vehicle is taking a turn on horizontal road - the necessary centripetal force is provided by whom? 

*At what maximum speed can a car safely negotiate a horizontal unbanked turn?

 *What force causes centripetal acceleration of a car making a turn on a flat road? 

*What type of force is responsible for keeping a car from skidding while moving around an unbanked curve?

Wall of death I Well of death | Spinning Room Amusement Park Ride - Analysis/Notes

 

In this video we try to understand (a) motion of a car moving well of death or a man stuck to the wall of a rotating drum (that has no base) (b) horizontal and vertical forces acting on this man. (c) the concept of Normal force. Hope you find this useful. You may like to increase speed to 1.25X or 1.5X. Thanks for watching / pl share.
