Effective Radius of Drum for Simple Band Brake Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effective radius of the drum = Radius of the drum+Thickness of Band/2
r_e = r_drum+t/2
This formula uses 3 Variables

Variables Used

Effective radius of the drum - (Measured in Meter) - The effective radius of the drum is the radius when the thickness of the band is also considered.
Radius of the drum - (Measured in Meter) - The radius of the drum is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length.
Thickness of Band - (Measured in Meter) - The thickness of band is the distance through an object, as distinct from width or height.

STEP 1: Convert Input(s) to Base Unit

Radius of the drum: 0.16 Meter --> 0.16 Meter No Conversion Required
Thickness of Band: 0.005 Meter --> 0.005 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_e = r_drum+t/2 --> 0.16+0.005/2

Evaluating ... ...

r_e = 0.1625

STEP 3: Convert Result to Output's Unit

0.1625 Meter --> No Conversion Required

FINAL ANSWER

0.1625 Meter <-- Effective radius of the drum

Tension in Band between First and Second Block for Band and Block Brake

Go Tension in band between the first and second block = Tension in Tight Side of the Band*(1-Coefficient of Friction for Brake*sin(Angle of Contact/2))/(1+Coefficient of Friction for Brake*sin(Angle of Contact/2))

Tension in Tight Side for Band and Block Brake

Go Tension in Tight Side of the Band = Tension in band between the first and second block*(1+Coefficient of Friction for Brake*sin(Angle of Contact/2))/(1-Coefficient of Friction for Brake*sin(Angle of Contact/2))

Tension in Tight Side of Band for Simple Band Brake

Go Tension in Tight Side of the Band = Tension in the slack side of band*e^(Coefficient of Friction for Brake*Angle of lap of band on the drum)

Tension in Tight Side of Band for Simple Band Brake given Permissible Tensile Stress

Go Tension in Tight Side of the Band = Permissible tensile strength*Width of Band*Thickness of Band

Effective Radius of Drum for Simple Band Brake

Go Effective radius of the drum = Radius of the drum+Thickness of Band/2

Effective Radius of Drum for Simple Band Brake Formula

Effective radius of the drum = Radius of the drum+Thickness of Band/2
r_e = r_drum+t/2
