Radial strain for rotating thin disc given initial radial width of disc Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radial strain = Increase in Radial Width/Initial Radial Width
e_r = du/dr
This formula uses 3 Variables

Variables Used

Radial strain - Radial strain is the change in length per unit length in a direction radially outward from the charge.
Increase in Radial Width - (Measured in Meter) - Increase in Radial Width is the increase in radial width due to strain.
