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 Slope of Road on Front Wheel?
Slope of Road on Front Wheel calculator uses Road Inclination Angle BRW = acos(Normal Reaction at Front Wheel BRW/(Vehicle Weight BRW*(Vehicle Wheelbase BRW-Horizontal Distance of C.G. from Rear Axle BRW)/(Vehicle Wheelbase BRW+Friction Coefficient between Wheels and Ground BRW*Height of C.G. of Vehicle BRW))) to calculate the Road Inclination Angle BRW, Slope of Road on Front Wheel formula is used to find the inclination of the road surface with the horizontal. Road Inclination Angle BRW is denoted by θ symbol.
How to calculate Slope of Road on Front Wheel using this online calculator? To use this online calculator for Slope of Road on Front Wheel, enter Normal Reaction at Front Wheel BRW (RF), Vehicle Weight BRW (W), Vehicle Wheelbase BRW (b), Horizontal Distance of C.G. from Rear Axle BRW (x), Friction Coefficient between Wheels and Ground BRW (μ) & Height of C.G. of Vehicle BRW (h) and hit the calculate button. Here is how the Slope of Road on Front Wheel calculation can be explained with given input values -> 571.6493 = acos(7103/(13000*(2.7-1.2)/(2.7+0.48*0.007919))).
