Homework Statement
A temperature controller, designed to work in a steam environment, involves a bimetallic strip constructed of brass and steel, connected at their ends by rivets. Each of the metals is t thick. At 20 degrees C, the strip is L0 long and straight. Find the radius of curvature of the assembly at 100 degrees C.
Homework Equations
The equation of linear thermal expansion and some circle geometry.
The Attempt at a Solution
Before I attempt anything, I would like to know if the radius of curvature includes the thickness of both metals. I would think so but I'm sure.
