Radial strain for rotating thin disc Solution

STEP 0: Pre-Calculation Summary
Formula Used
Radial Strain = (Final Radial Width-Initial Radial Width)/Initial Radial Width
εr = (drf-dr)/dr
This formula uses 3 Variables
Variables Used
Radial Strain - Radial strain is the change in length per unit of original length in the radial direction (the direction from the center to the outer edge of an object).
Final Radial Width - (Measured in Meter) - Final radial width refers to the change or the final measurement of the distance from the center of an object to its outer edge after some transformation or process.
Initial Radial Width - (Measured in Meter) - Initial radial width the starting radial distance or width at a particular point or state.
STEP 1: Convert Input(s) to Base Unit
Final Radial Width: 9 Millimeter --> 0.009 Meter (Check conversion ​here)
Initial Radial Width: 3 Millimeter --> 0.003 Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
εr = (drf-dr)/dr --> (0.009-0.003)/0.003
Evaluating ... ...
εr = 2
STEP 3: Convert Result to Output's Unit
2 --> No Conversion Required
FINAL ANSWER
2 <-- Radial Strain

What is the allowable stress?

Allowable stress, or allowable strength, is the maximum stress that can be safely applied to a structure. Allowable stress is the stress at which a member is not expected to fail under the given loading conditions.
