An unbalanced centrifugal pump of mass 50kg produces an out-of-balance force of 2kN and is supported by four springs (Figure B2). Each spring has stiffness constant 10kN/m as shown. If th pump operates at 800rpm, determine: a) the total spring stiffness" b) the natural frequency c) the driving frequency(. the steady-state amplitude of vibration (ignore initial conditions). d)
