## Radius of the Drum Brake When Braking Torque is Given Solution

STEP 0: Pre-Calculation Summary
Formula Used
radius_of_drum = Braking or fixing torque on the fixed member/Coefficient of Friction*Normal reaction
r = T3/μ*Rn
This formula uses 3 Variables
Variables Used
Braking or fixing torque on the fixed member - Braking or fixing torque on the fixed member is the measure of the force that can cause an object to rotate about an axis. (Measured in Newton Centimeter)
Coefficient of Friction- The Coefficient of Friction (μ) is the ratio defining the force that resists the motion of one body in relation to another body in contact with it. This ratio is dependent on material properties and most materials have a value between 0 and 1.
Normal reaction - Normal reaction is the force exerted by a surface on an object in contact with it which prevents the object from passing through the surface (Measured in Newton)
STEP 1: Convert Input(s) to Base Unit
Braking or fixing torque on the fixed member: 33 Newton Centimeter --> 0.33 Newton Meter (Check conversion here)
Coefficient of Friction: 0.2 --> No Conversion Required
Normal reaction: 4 Newton --> 4 Newton No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
r = T3/μ*Rn --> 0.33/0.2*4
Evaluating ... ...
r = 6.6
STEP 3: Convert Result to Output's Unit
6.6 Meter -->6600 Millimeter (Check conversion here)
FINAL ANSWER
6600 Millimeter <-- Radius of the drum
(Calculation completed in 00.016 seconds)

### Radius of the Drum Brake When Braking Torque is Given Formula

radius_of_drum = Braking or fixing torque on the fixed member/Coefficient of Friction*Normal reaction
r = T3/μ*Rn

## Define Braking Torque?

Brake torque is essentially the power of the braking system. The force exerted by the caliper, multiplied by the effective radius of the system equals the brake torque. Increasing either the force applied by the caliper, or the effective radius results in increased brake torque.
