Braking distribution among front and rear brakes
It is observed that in vehicles either the distribution of weight over the two axles is equal, or the front axle carries more weight, the braking effect has to be more at the front wheels for efficient braking. It is seen that in general for achieving maximum efficiency, about 75% of the total braking effect should be on front wheels. However, in such case the trouble would arise while travelling over wet road. where hight braking effect at the front would cause skidding of front wheels, because of decrease of weight transfer. In practice, about 60% of the braking effort is applied on the front wheels.
How to Calculate Friction Coefficient between Wheel and Road Surface on Rear Wheel?
Friction Coefficient between Wheel and Road Surface on Rear Wheel calculator uses Friction Coefficient between Wheels and Ground BRW = (Normal Reaction at Rear Wheel BRW*Vehicle Wheelbase BRW-Vehicle Weight BRW*Horizontal Distance of C.G. from Rear Axle BRW*cos(Road Inclination Angle BRW))/(Height of C.G. of Vehicle BRW*(Vehicle Weight BRW*cos(Road Inclination Angle BRW)-Normal Reaction at Rear Wheel BRW)) to calculate the Friction Coefficient between Wheels and Ground BRW, Friction Coefficient between Wheel and Road Surface on Rear Wheel formula is used to find the measure of the amount of friction existing between ground and wheel. Friction Coefficient between Wheels and Ground BRW is denoted by μ symbol.
How to calculate Friction Coefficient between Wheel and Road Surface on Rear Wheel using this online calculator? To use this online calculator for Friction Coefficient between Wheel and Road Surface on Rear Wheel, enter Normal Reaction at Rear Wheel BRW (RR), Vehicle Wheelbase BRW (b), Vehicle Weight BRW (W), Horizontal Distance of C.G. from Rear Axle BRW (x), Road Inclination Angle BRW (θ) & Height of C.G. of Vehicle BRW (h) and hit the calculate button. Here is how the Friction Coefficient between Wheel and Road Surface on Rear Wheel calculation can be explained with given input values -> -2.623568 = (5700*2.7-13000*1.2*cos(0.1745329251994))/(0.007919*(13000*cos(0.1745329251994)-5700)).
