the bimetallic strip has a thickness x and is straight at temp T.
What is the radius of curvature of the strip, R, when it is heated to temp T+dT
Coeff. of linear expansion: a1, a2.
Assume each each metal has a thickness of x/2 and X<<R
The Attempt at a Solution
I was givin the hint that:
Where on Earth do this +-x/4 come from?!
