Actuating Force Solution

STEP 0: Pre-Calculation Summary

Formula Used

Actuating force on brake = Average Pressure on Brake*Area of Brake Pad
F = P_avg*A
This formula uses 3 Variables

Variables Used

Actuating force on brake - (Measured in Newton) - Actuating force on brake is defined as the amount of force required to actuate the braking mechanism.
Average Pressure on Brake - (Measured in Pascal) - Average Pressure on brake is defined as the normal force acting per unit area onto the brakes.
Area of Brake Pad - (Measured in Square Meter) - Area of Brake Pad is the actual area of the brake pad that we are using in a disk brake or a drum brake.

STEP 1: Convert Input(s) to Base Unit

Average Pressure on Brake: 2 Megapascal --> 2000000 Pascal (Check conversion here)
Area of Brake Pad: 5500 Square Millimeter --> 0.0055 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F = P_avg*A --> 2000000*0.0055

Evaluating ... ...

F = 11000

STEP 3: Convert Result to Output's Unit

11000 Newton --> No Conversion Required

FINAL ANSWER

11000 Newton <-- Actuating force on brake

(Calculation completed in 00.004 seconds)

Friction Radius of Disk Brake

Go Friction Radius of Brake = 2*(Brake Pad Outer Radius^3-Brake Pad Inner Radius^3)/(3*(Brake Pad Outer Radius^2-Brake Pad Inner Radius^2))

Outer Radius of Brake Pad given Area of Brake Pad

Go Brake Pad Outer Radius = sqrt((2*Area of Brake Pad/Angular Dimension of Pad)+Brake Pad Inner Radius^2)

Inner Radius of Brake Pad given Area of Brake Pad

Go Brake Pad Inner Radius = sqrt(Brake Pad Outer Radius^2-(2*Area of Brake Pad/Angular Dimension of Pad))

Coefficient of Friction given Torque Capacity of Disk Brake

Go Coefficient of Friction for Brake = Torque absorbed by brake/(Actuating force on brake*Friction Radius of Brake)

Actuating Force given Torque Capacity of Disk Brake

Go Actuating force on brake = Torque absorbed by brake/(Coefficient of Friction for Brake*Friction Radius of Brake)

Friction Radius given Torque Capacity of Disk Brake

Go Friction Radius of Brake = Torque absorbed by brake/(Coefficient of Friction for Brake*Actuating force on brake)

Torque Capacity of Disk Brake

Go Torque absorbed by brake = Coefficient of Friction for Brake*Actuating force on brake*Friction Radius of Brake

Angular Dimension of Pad given Area of Brake Pad

Go Angular Dimension of Pad = 2*Area of Brake Pad/(Brake Pad Outer Radius^2-Brake Pad Inner Radius^2)

Area of Brake Pad

Go Area of Brake Pad = Angular Dimension of Pad*(Brake Pad Outer Radius^2-Brake Pad Inner Radius^2)/2

Average Pressure given Actuating Force

Go Average Pressure on Brake = Actuating force on brake/Area of Brake Pad

Area of Pad given Actuating Force

Go Area of Brake Pad = Actuating force on brake/Average Pressure on Brake

Actuating Force

Go Actuating force on brake = Average Pressure on Brake*Area of Brake Pad

Actuating Force Formula

Actuating force on brake = Average Pressure on Brake*Area of Brake Pad
F = P_avg*A

Define Actuating Force?

Actuating force means the force required to set the actuating mechanism. Once the actuating force is applied, the friction generated at the shoe acts to increase the braking torque.
