1.1 A link is a part of a machine that has motion relative to another part. A mechanism is a system of links connected together to transmit motion or perform work.
DOF = 3(n-1) - 2f - h
where x is the displacement of the machine, c is the damping coefficient, and F0 is the amplitude of the external force. Mechanics Of Machines 2nd Edition Solution Manual Pdf
4.3 The equation of motion for a vibrating machine can be written as: c is the damping coefficient
ωo = ωi × (N1 / N2)
