If friction is zero , can a vehicle move on the road ? Why are we not considering the friction in deriving the expression for the banking angle ?

A car is negotiating a curved road of radius R. The road is banked at angle theta . The coefficeint of friction between the tyres of the car and the road is mu_(s) . The maximum safe velocity on this road is

While driving along an unbanked circular road, a two- wheeler ride has to lean with the vertical. Why is it so? With what angle the rider has to lean? Derive the relevant expression . Why such a leaning is not necessary for a four wheeler?

Part of a racing track is to be designed for a curvature of 72 m. We are not recommending the vehicles to drive faster than 216 kmph. With what angle should the road be tilted? By what height will its outer edge be, with respect to the inner edge if the track is 10m wide?

Derive an expression for most safe speed of a vehicle on a curved banked road ignoring friction.

Fill in the blanks and complete the following paragraph . (words given: upward, friction,negligible,downward , gravitational , buoyance , very large, electric) When a body falls in air, there are three forces acting on the body : (1) the gravitational force due to the earth, acting........(2) the force of ........ due to air, acting .....(3) the force due to...... with air, acting in the direction oppositeto that of the velocity of the body. Under certain conditions, the force of buoyancy due to air and friction with air can be....... compared to the.......force of the earth. In that case (near the earth's surface) the body falls with almost uniform acceleration (g). Whenever a body moves under the influence of the force of gravity alone, it is said to be falling freely. Strictly speaking, this is true only if the body falls in vaccum.

Derive an expression for most safe speed of a vehicle moving on a curved banked road ignoring friction?

The curved horizontal road is banked at an angle theta . What will happen to a vehicle moving along this road if : theta' < theta . Where theta is the angle of banking for given road.

The maximum speed with which a vehicle can negotiate a cuved road, which is banked at the angle theta=tan^-1(0.24) is 54 km//hr . IF the same road is flat and vehicle has to negotiate the curve with same maximum speed, the coefficient of friction between the road and tyres of the vehicle should be
