A mass supported on a nonlinear spring is subjected to an impulsive force F(t) and thereafter undergoes free
vibration. The spring stiffness is characterized by the force-deflection curve shown below. Determine the maximum deflection ymax of the mass. Compare results with those of VM74. Figure 79.1 Bilinear Spring Assembly Problem Sketch Material P...
