Abstract
Cantilevers can be found all around us, and they include objects such as signs, diving boards, and horizontal flagpoles. The cantilever beam is a key concept in civil engineering, and it is used in the construction of buildings, bridges, and balconies. An equation for the deflection of cantilever beams from certain loads was discovered in 1750 by Euler and Bernoulli, and this equation can be used to deeply explore the physics of the cantilever beam. Strain gauges can be attached to a cantilever beam, and from the strain values we can determine the stress and the Young’s Modulus of the material. A double-exposure hologram of a cantilever can be used to find the wavelength of the light and the Young’s Modulus of the cantilever beam.
