The apparatus instructions provide a formula: (deflection) = [(Load)(beam
length cubed)] / [4(beam width)(beam height cubed)(Young's modulus)].
Graphing deflection vs load (for constant length) or deflection vs beam
length cubed (for constant load) should then give a straight line from which
Young's modulus is calculated as a factor of the slope.
