Homework Statement
If you have two materials of equal length and radius and then you join them together.
Material 1 young's modulus = y1
material 2 young's modulus = y2
Homework Equations
F/a = y Lchange / Lo
The Attempt at a Solution
Given they are of the same length and radius. Is the "new" youngs modulus simply their weighted average:
ynew = 0.5 * (y1 + y2)
