Question

derive an expression for the lower speed limit and upper speed limit for the vehicle moving along the banked road​

Answer 1

Explanation:

In this condition friction is zero.

so see pic and get solution

Answer 2

Expression for the lower speed limit and upper speed limit:

Explanation:

• The upward part, N cosθ balances the part fs sin θ and weight 'mg'.
• This is an articulation for most extreme security speed with which a vehicle can be securely determined along a bended banked street (thinking about rubbing).
• The point of banking relies upon the speed of the vehicle, the range of the bended street and the speed increase because of gravity g at that spot.
• The articulation doesn't contain the term m addressing mass, consequently the point of banking is free of mass 'm' of the vehicle.
