A car of mass 1 tonne travels round an unbanked horizontal curve of radius 28m. The track width of the car is 1.6m and its centre of gravity is central and at a height of 0.85m above the road surface. The limiting coefficient of friction between the tyres and the road is 0.65. (a) Show whether the car is likely to skid or overturn if the speed is excessive. (b) What is the maximum speed in km/h at which it can safely travel around the curve (c) Determine the reactions of the inner and outer wheels at this maximum speed

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
