WebEquilibrium method or Newton’s method Consider a constraint (i.e.Spring) of negligible mass in an unstrainded. Let S = Stiffness of the constraint. It is the force required to produce unit displacement in the direction of vibration. It is usually expressed in N/ M. m = Mass of the body suspended from the constraint in kg, WebSep 24, 2007 · Dunkerely's method tells us that if we have a system of discrete springs and masses, we can combine the resonant frequencies associated with each single mass alone attached to the system of springs using: 1/w^2 = 1/w1^2 + 1/w2^2 + .... The only proof I have seen of Dunkerley's method uses discrete masses.
