Question B1. A 250 kg machine rests on a resilient foundation modelled as spring and damper (Figure QB1). Under the weight of the machine the static deflection of the foundation is 24.525 mm. The foundation's damping coefficient is 1291 Ns/m. m y(t) m. Figure QB1. Machine on elastic foundation modelled as a spring-mass-damper system a. Determine the resonant frequency of the system [5 Marks] b. Determine the steady-state amplitude of the vibration of the mass at resonance if the amplitude of the motion of the base is Y = 0.5 cm. (Assume sinusoidal motion of the base). [10 Marks] c. Determine the force transmitted to the base through the foundation at resonance. [10 Marks]
