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)
“What, really, is wanted from a neighborhood? Convenience, certainly, an absence of major aggravation, to be sure. But perhaps most of all, ideally, what is wanted is a comfortable background, a breathing space of intermission between the intensities of private life and the calculations of public life.”
—Joseph Epstein (b. 1937)
“The vulgar call good fortune that which really is produced by the calculations of genius.”
—Ralph Waldo Emerson (1803–1882)
