The pipe coming out of the pump is experiencing excessive vibrations. The pipe can be modeled as an SDOF system. The stiffness can be calculated by measuring the deflection (1 cm) when a force of 200 N is placed on the pipe. Additionally, a push test (pushing the pipe and letting it vibrate) showed that the natural frequency of the system is approximately 1 Hz. If the pipe vibrates at a frequency of 5 Hz during operation, design an undamped tuned absorber system considering that the absorber mass should not vibrate more than 1 mm.
