Resistance during vehicle moving condition: The moving vehicle has to overcome the following resistances: 1.     Air or wind resistance, 2.     Gradient resistance, and 3.     Rolling resistance. Air resistance Is the aerodynamic drag experienced by the vehicle while moving and depends upon the frontal area of the vehicle speed and the speed of the vehicle. Gradient resistance Depends u[on the weight of the vehicle and the steepness or the grade of the road. It is independent of the speed of the vehicle. Rolling resistance Is the resistance to rolling occurring due to the deformation of road and tyre and the losses occurring due to the dissipation of energy in the tyre. The factors which affect rolling resistance are mainly the inflation pressure of the tyre design. The effect of speed is rather negligible . How overcome these resistances? To overcome this high torque is required at the driving wheels when a vehicle ...

                      Centrifugal clutch Intro Centrifugal clutch is mainly used in automatic gear system .compare to other clutch types its costly   but it has more advantages then other system. Working The centrifugal clutch automatically disengages itself when the speed falls below and engages when the speed rises above a pre-set value. centrifugal bob-weight are positioned in such a way that the centrifugal forces exerted by them with the clutch rotation result in the release levers due to the outer end of the release lever moving towards the flywheel . This results in the proportionate increase of centrifugally generated pressure with the increase of engine speed. Therefore at low engine speeds only the spring pressure acts, while at high engine speeds the force generated by the weights supplements the spring pressure. Thus smooth and acceptable gear changes...

                                Centrifugal force Why I’m suddenly jumped to force you may get confused .so don’t get into anything my next topic is centrifugal clutch so that the reason I’m telling about this force ok now we see   what its?? Centrifugal force meaning center and f ugere meaning to   flee the force that draws a rotating body away from the center of rotation .it is caused by the inertia of the body’s path is continually redirected.
