PROBLEM: Represent the translational mechanical system shown in Figure 3.15 in state space about the equilibrium displacement. The spring is nonlinear, where the relationship between the spring force, f,(t), and the spring displacement, x,(t), is f,(t) = 2x(t). The applied force is f(t) = 10+ f (t), where of(t) is a small force about the 10 N constant value. Assume the output to be the displacement of the mass, x(t).

PROBLEM: Represent the translational mechanical system shown in Figure 3.15 in state
space about the equilibrium displacement. The spring is nonlinear, where the relationship
between the spring force, f,(t), and the spring displacement, x,(t), is f,(t) = 2x(t).
The applied force is f(t) = 10+ f (1), where of(t) is a small force about the 10 N
constant value.
