Calculations
Curvature of a Bimetallic Beam:
Where and are the Young's Modulus and height of Material One and and are the Young's Modulus and height of Material Two. is the misfit strain, calculated by:
Where α1 is the Coefficient of Thermal Expansion of Material One and α2 is the Coefficient of Thermal Expansion of Material Two. ΔT is the current temperature minus the reference temperature (the temperature where the beam has no flexure).

Famous quotes containing the word calculations:
“Nowhere are our calculations more frequently upset than in war.”
—Titus Livius (Livy)
“He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in physics because they are true in ethics.”
—Henry David Thoreau (1817–1862)
“Heaven’s calculations don’t follow man’s calculations.”
—Chinese proverb.
