consider a circular road of radius 20 meter banked at an angle of 15°with what speed the car has to move so that it will have a safe turn |
|
Answer» :Radius of circular path = 20mAngle of banking = 15°We have to find maximum safe speed of the car★ Banking of tracks (roads) : The maximum velocity with which a vehicle (in the absence of FRICTION) can NEGOTIATE a circular ROAD of radius r and baked at an angle θ is given by v²= rg tanθBy substituting the given values,➝ v² = 20 × 10 × tan15°➝ v² = 200 × 0.27➝ v = √54➝ v = 7.35 m/s★ KNOW more :A VEHIE taking a circular turn on a level road. If μ is the coefficient of friction b/w thres and road, then the maximum velocity with which the vehicle can safely take a circular turn at radius r is given byv = √(μ r g) |
