## Collar friction torque in accordance of Uniform Pressure Theory Solution

STEP 0: Pre-Calculation Summary
Formula Used
collar_friction_torque = ((Coefficient of Friction*Load)*((Outer dia of a collar)^3-(Inner dia of a collar)^3))/(3*((Outer dia of a collar)^2-(Inner dia of a collar)^2))
T c = ((μ*W)*((d0)^3-(di)^3))/(3*((d0)^2-(di)^2))
This formula uses 4 Variables
Variables Used
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.
Load - Load is the instantaneous load applied perpendicular to the specimen cross section. (Measured in Newton)
Outer dia of a collar - The outer dia of a collar is the actual outer diameter of the collar. (Measured in Millimeter)
Inner dia of a collar - The inner dia of a collar is actual inner diamter of the collar. (Measured in Millimeter)
STEP 1: Convert Input(s) to Base Unit
Coefficient of Friction: 0.2 --> No Conversion Required
Load: 1000 Newton --> 1000 Newton No Conversion Required
Outer dia of a collar: 100 Millimeter --> 0.1 Meter (Check conversion here)
Inner dia of a collar: 50 Millimeter --> 0.05 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
T c = ((μ*W)*((d0)^3-(di)^3))/(3*((d0)^2-(di)^2)) --> ((0.2*1000)*((0.1)^3-(0.05)^3))/(3*((0.1)^2-(0.05)^2))
Evaluating ... ...
T c = 7.77777777777778
STEP 3: Convert Result to Output's Unit
7.77777777777778 Newton Meter -->7777.77777777778 Newton Millimeter (Check conversion here)
7777.77777777778 Newton Millimeter <-- Collar Friction Torque
