Therefore, the amplitude of the pendulum’s oscillation is A =0.140 m = 14.0 cm. Example 2 Assume that the head of a jack-in-the-box toy is bouncing upward and downward on a spring. Furthermore, the angular frequency of the oscillation isω=π/6radians/s, and the phase shift isϕ...

Formula (4) is restricted to only very small values of damping, and for a softening system with considerable values of stiffness nonlinearity, it gives incorrect solutions in the area of maximum possible oscillation amplitudes of the system. Moreover, formula (4) gives exact (steady-state) ...
Harmonic oscillations are given by functions sin(ωt) or cos(ωt), where ω = 2πv, and v is the oscillation frequency and ω is the circular frequency.4 Another useful and widely used mathematical notation for harmonic oscillations is (Euler formula) (2.5)eiωt=cos(ωt)+isin(ωt) Fo...
Table 1. Experiment formula. Three types of rubber springs were tested. Figure 3 shows the layout of ST, CT and SCCT rubber springs. The ST rubber spring test was conducted by clamping two ST rubber springs using two rigid metal plates with four bolts, which were also used to control tr...

turn leads to a second drop in wall pressure values. At 0.0799 s, the tail car passes the measurement point, and thereby, the downward trend of the wall pressure curve ends. The measured value starts to rise until it returns to its initial state and stabilizes after a small oscillation. ...
