Braking Efficiency Solution

STEP 0: Pre-Calculation Summary
Formula Used
Braking Efficiency = (Braking Force on Brake Drum/Weight of Vehicle)*100
η = (F/W)*100
This formula uses 3 Variables
Variables Used
Braking Efficiency - Braking Efficiency is defined as the braking force produced as a percentage of the total weight of the vehicle.
Braking Force on Brake Drum - (Measured in Newton) - Braking Force on Brake Drum is defined as the force acting on the brake drum by the brake shoe when the braking is actuated by the driver.
Weight of Vehicle - (Measured in Newton) - Weight of Vehicle is the heaviness of the vehicle, generally expressed in Newtons.
STEP 1: Convert Input(s) to Base Unit
Braking Force on Brake Drum: 7800 Newton --> 7800 Newton No Conversion Required
Weight of Vehicle: 13000 Newton --> 13000 Newton No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
η = (F/W)*100 --> (7800/13000)*100
Evaluating ... ...
η = 60
STEP 3: Convert Result to Output's Unit
60 --> No Conversion Required
FINAL ANSWER
60 <-- Braking Efficiency

12 Wheel Centre Rates for Independent Suspension Calculators

Assumed Initial Roll Rate given Required Anti-Roll Bar Rate
Go Assumed Initial Roll Rate = (Required Anti Roll Bar Rate+Wheel Centre Rate*(Track Width of Vehicle^2)/2)*(Tyre Vertical Rate*(Track Width of Vehicle^2)/2)/(Tyre Vertical Rate*(Track Width of Vehicle^2)/2+Required Anti Roll Bar Rate+Wheel Centre Rate*(Track Width of Vehicle^2)/2)
Tyre Rate given Required Anti-Roll Bar Rate
Go Tyre Vertical Rate = (((Required Anti Roll Bar Rate+Wheel Centre Rate*(Track Width of Vehicle^2)/2)*Assumed Initial Roll Rate)/((Required Anti Roll Bar Rate+Wheel Centre Rate*(Track Width of Vehicle^2)/2)-Assumed Initial Roll Rate))*2/Track Width of Vehicle^2
Wheel Centre Rate given Required Anti-Roll Bar Rate
Go Wheel Centre Rate = (Assumed Initial Roll Rate*(Tyre Vertical Rate*(Track Width of Vehicle^2)/2)/(Tyre Vertical Rate*(Track Width of Vehicle^2)/2-Assumed Initial Roll Rate)-Required Anti Roll Bar Rate)/((Track Width of Vehicle^2)/2)
Required Anti-Roll Bar Rate
Go Required Anti Roll Bar Rate = Assumed Initial Roll Rate*(Tyre Vertical Rate*(Track Width of Vehicle^2)/2)/(Tyre Vertical Rate*(Track Width of Vehicle^2)/2-Assumed Initial Roll Rate)-Wheel Centre Rate*(Track Width of Vehicle^2)/2
Power Absorbed by Disc Brake
Go Power Absorbed by Disc Brake = 2*Line Pressure*Area of One Piston per Caliper*Coefficient of Friction of Pad Material*Mean Radius of Caliper unit to Disc Axis*Number of Caliper Units*2*Number of Caliper Units*Revolution of Discs per Minute/60
Area of Brake Lining
Go Area of Brake Lining = (Brake Lining Width*Brake Drum Radius*Angle between Linings of Brake Shoes*pi)/180
Ride Rate given Wheel Centre Rate
Go Ride Rate = (Tyre Vertical Rate*Wheel Centre Rate)/(Tyre Vertical Rate+Wheel Centre Rate)
Wheel Centre Rate
Go Wheel Centre Rate = (Ride Rate*Tyre Vertical Rate)/(Tyre Vertical Rate-Ride Rate)
Tyre Vertical Rate given Wheel Centre Rate
Go Tyre Vertical Rate = (Wheel Centre Rate*Ride Rate)/(Wheel Centre Rate-Ride Rate)
Work Done in Braking
Go Work done in Braking = Braking Force on Brake Drum*Stopping Distance during Braking in Meters
Brake Fluid Pressure
Go Brake Fluid Pressure = Force Produced by Master Cylinder/Area of Master Cylinder Piston
Braking Efficiency
Go Braking Efficiency = (Braking Force on Brake Drum/Weight of Vehicle)*100

Braking Efficiency Formula

Braking Efficiency = (Braking Force on Brake Drum/Weight of Vehicle)*100
η = (F/W)*100

What is braking efficiency?

The braking efficiency is the ability of the brake to reduce the vehicle speed up to a possible stop, to maintain a certain speed of the descending vehicle on a slope, or to keep the vehicle on a slope. Braking efficiency means the maximum braking force capable of being developed by the brakes of a vehicle, expressed as a percentage of the weight of the vehicle including any persons or load carried in the vehicle.

How to Calculate Braking Efficiency?

Braking Efficiency calculator uses Braking Efficiency = (Braking Force on Brake Drum/Weight of Vehicle)*100 to calculate the Braking Efficiency, The Braking efficiency formula is defined as the braking force produced as a percentage of the total weight of the vehicle. Braking Efficiency is denoted by η symbol.
