A gold-alloy microbeam attached to a silicon wafer behaves like a cantilever beam subjected to a uniform load (see figure).
The beam has a length L = 24.5 um and rectangular cross section of a width b = 4.0 pm and thickness t = 0.88 um. The total load on the beam is 14.9 µN. If the deflection at the end of the beam is 1.53 um, what is the modulus of elasticity E, of the gold alloy (in
GPa)? (Use the formulas of this example. The beam has constant flexural rigidity EI.)
