Thomson, Vibration Theory and Applications, 2nd Printing, Prentice-Hall, Inc., Englewood Cliffs, NJ, 1965, pg. 56, ex. 3.1-2. Analysis Type(s): Reduced Harmonic Response Analysis (ANTYPE = 3) Element Type(s): Combination Elements (COMBIN40) Input Listing: vm86.dat Test Case A machine of weight W is supported on springs of total stiffness k. If a harmonic disturbing force of magnitude F1 and frequency f (equal to the natural frequency of the machine, fn) acts on the machine, determine the displacement response in terms of the peak amplitude Ao and phase angle Φ. Assume a viscous damping coefficien...
