The electrodynamic shaker of Figure P18.49 is used to perform vibration testing of an electrical connector. The connector is placed on the test platform (with mass m), and it may be assumed to have negligible mass when compared to the platform. The test consists of shaking the connector at the frequency ? = 2? × 100 rad/s. Given the parameter values B = 1,000 Wb/m2, l = 5 m, k = 1,000 N/m, m = 1 kg, b = 5 N-s/m, L = 0.8 H, and R = 0.5 ?, determine the peak amplitude of the sinusoidal voltage VS required to generate an acceleration of 5g (49 m/s2).
