Context 1

... vibrating system is commonly modeled with a mass supported by a spring and carried by a moving belt through friction ( Figure 1). In this approach it is noticed that friction coefficient decreasing with velocity can make the system unstable. ...

Context 2

... model of vibrating system is considered in Figure 1. A solid of mass m in position x is fixed to a wall through a spring of stiffness k and viscous damping ratio c. ...
