Area of Brake Pad Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area of Brake Pad = Angular Dimension of Pad*(Brake Pad Outer Radius^2-Brake Pad Inner Radius^2)/2
A = θ_pad*(R_o^2-R_i^2)/2
This formula uses 4 Variables

Variables Used

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.
Angular Dimension of Pad - (Measured in Radian) - Angular Dimension of Pad specifies the angle of the annular pad.
Brake Pad Outer Radius - (Measured in Meter) - Brake Pad Outer Radius is defined as the outer radius of the brake pad.
Brake Pad Inner Radius - (Measured in Meter) - Brake Pad Inner Radius is defined as the inner radius of the brake pad.

STEP 1: Convert Input(s) to Base Unit

Angular Dimension of Pad: 1.98 Radian --> 1.98 Radian No Conversion Required
Brake Pad Outer Radius: 125 Millimeter --> 0.125 Meter (Check conversion here)
Brake Pad Inner Radius: 100 Millimeter --> 0.1 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = θ_pad*(R_o^2-R_i^2)/2 --> 1.98*(0.125^2-0.1^2)/2

Evaluating ... ...

A = 0.00556875

STEP 3: Convert Result to Output's Unit

0.00556875 Square Meter -->5568.75 Square Millimeter (Check conversion here)

A = θ_pad*(R_o^2-R_i^2)/2

Define Disk Brake?

A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary.

How to Calculate Area of Brake Pad?

Area of Brake Pad calculator uses Area of Brake Pad = Angular Dimension of Pad*(Brake Pad Outer Radius^2-Brake Pad Inner Radius^2)/2 to calculate the Area of Brake Pad, Area of Brake Pad formula is defined as area of annular brake pads that are used in disk brakes. Area of Brake Pad is denoted by A symbol.

How to calculate Area of Brake Pad using this online calculator? To use this online calculator for Area of Brake Pad, enter Angular Dimension of Pad (θ_pad), Brake Pad Outer Radius (R_o) & Brake Pad Inner Radius (R_i) and hit the calculate button.
