DISPLAY
A plate consisting of two materials has its temperature raised.
Becuse the thermal expansion coefficients of the two materials
differ by a factor of 10, the plate distorts. its radius of
curvature being proportional to the width of the plate in the
direction normal to the line of separation between the materials,
divided by the differences in thermal strain.
The opportunity is provided for the plate to be held either at its
high-y or low-y edges.
