Bridge behavior must be studied together with the flexing top plate.

Evidence

The growing consensus is that studies of the bridge alone, as if seated in concrete, are less useful than considering the bridge to be rocking and flexing with the top plate. (However, the rocking is not symmetric, because one foot of the bridge sits just over the soundpost, which connects directly to the back plate, imparting more stiffness to it than to the other foot, which sits just over the bassbar, a strip of wood running longitudinally that stiffens the top plate.) — Eric J. Heller, Why You Hear What You Hear- An…, 1776
