A gold-alloy microbeam attached to a silicon wafer behaves like a cantilever beam subjected to a uniform

Question:

A gold-alloy microbeam attached to a silicon wafer behaves like a cantilever beam subjected to a uniform load (see figure). The beam has length L = 27.5 Î¼m and rectangular cross section of width b = 4.0 Î¼m and thickness t = 0.88 Î¼m.
The total load on the beam is 17.2 Î¼N. If the deflection at the end of the beam is 2.46 Î¼m, what is the modulus of elasticity Eg of the gold alloy?
