Compute the response of the system in Figure 3.26 for the case that the damping is linear viscous, the spring is a nonlinear soft spring of the form

and initial conditions of x0 = 0.01 m and 0 = 1.0 m/s. The system has a mass of 100 kg, a damping coefficient of 30 kg/s, and a linear stiffness coefficient of 2000 N/m. The value of k1 is taken to be 300 N/m3 . Compute the solution and compare it to the linear solution (k1 = 0). Which system has the largest magnitude? Compare your solution to that of Example 3.10.1.
Example 3.10.1
Compute the response of the system in Figure 3.26 for the case that the damping is linear viscous, the spring is a nonlinear “hardening” spring of the form
