ROTATIONAL DYNAMICS

 ROTATIONAL DYNAMICS

MAXIMUM SPEED ON HORIZONTAL ROAD

 LET  

 Fs   IS FRICTION FORCE BETWEEN ROAD AND TYRE

m is the mass of vehicle 

mg is the mass due to gravity

v is the velocity of vehicle

mu is the coefficient of friction

N  is the normal reaction

centripetal force = Fs

centrifugal force = mv.v/r

 

forces acting on the vehicle while taking turn on horizontal road 

 

mg = N   ................ eq (1)

Fs = centrifugal force ..........(2)

here Fs = mu.N        

takin ratio of eq 1 and 2
