Wave Speed on a String under Tension. To see how the speed of a wave on a string depends on the tension and the linear density, consider a pulse sent down a taut string (Figure 16.4.1 ). When the taut string is at rest at the equilibrium position, the tension in the string FT is constant. Consider a small element of the string with a mass equal ...

Linear time-invariant vibrating systems are considered. The method is also extended to systems with asymmetric matrices, by proposing a more general formulation of the receptance-based zero-assignment method in the case of rank-one control. A two-stage approach is proposed. In the first stage, that exploits the good numerical conditioning of ...

This mechanism mainly has two parts: a linear vibrating magnet (LVM) fixed on the excitation source and a rotatable cylinder with a magnets array (CMA). The reciprocating motion of the LVM will generate oscillatory magnetic forces on the magnet array (MA), creating a time-varying torque on the cylinder and driving it to turn around.
