Question: A micro cantilever is placed on a shaker that provides a variable-frequency input displacement motion u = 5 sin(~t) nm. The micro cantilever has a length l = 320 nm, width w = 50 nm, thickness h = 3 nm, Young's modulus E = 150 Gpa, mass density t = 5400 kg/m3 and is used in conjunction with a strain gauge (Kg = 2.1) attached to the cantilever root and connected in a Wheatstone bridge (with vi = 20 nV). Knowing that the maximum voltage readout is DV₀ = 8 n_V, determine the overall coefficient of viscous damping c.
