A two degree of freedom system is one that requires two coordinates to completely describe its equation of motion. These coordinates are called generalized coordinates when they are independent of each other. Thus system with two degrees of freedom will have two equation of motion and hence has two frequencies.

Draw a free body diagram and derive the equations of motion for a three degrees-of-freedom system, with three di erent masses, four di erent springs, and no forcing. Put them in matrix form. Your result should resemble equation (1.4) except your matrix will be 3x3 and you will have no f(t) term.
23 mar 2017 · This document discusses two degree of freedom systems and provides equations of motion for a two degree of freedom spring-mass system with damping. It presents the matrix form of the equations of motion and defines the mass, damping and stiffness matrices.
Hence λ is the Eigen value of [-1] and this may be found easily with computer packages such as Mathcad. The method can be used to solve problems with three or more degrees of freedom. There is a natural frequency for each degree. The method can be used for any two degree of freedom system in which the stiffness and mass matrices
• There are two equations for a two degree of fdfreedom system, one for each mass (precisely one for each degree of freedom). • They are generally in the form of coupled differential equations‐that is, each equation involves all the coordinates.
