Unformatted text preview: + 2 2 8 2 ± (64 − 8 2 ) cos 8 t + (2)(8) sin 8 t ² = 1 4 sin 8 t . The resonant frequency for the system is γ r / (2 π ), where γ r is given in (15), Section 4.9. Applying this formula, we get resonant frequency = 1 2 π r k m − b 2 2 m 2 = 1 2 π s 64 1 − 2 2 2(1 2 ) = √ 62 2 π . 257...
