An unbalanced centrifugal pump of mass 50kg produces an out-of-balance force of 2kN and is supported by four springs. Each spring has stiffness constant 10KN/m as shown. If the pump operates at 800rpm, determine the natural frequency of the system. Pump O wn = 30 rad/s O wn 20 rad/s Own = 28. 28 rad/s O wn 14. 14 rad/s
