Question
Chapter 16, Problem 16.29P
Interpretation Introduction
Interpretation:
Whether the replacement of the polymer part as scheduled will prevent the failure or not should be determined.
Concept Introduction:
When under constant load, thermoplastics shows creep, a time-dependent permanent deformation. It also shows stress relaxation which is decrease in the stress level with time under constant strain.

If you have a spring mass damper system, given by m*x_double_dot + c*x_dot + kx = 0 where m, c, k (all positive scalars) are the mass, damper coefficient, and spring coefficient, respectively. x ∈ R represents the displacement of the mass.
Let us then discuss the stability of the system by using Lyapunov stability theorem. Consider the system energy as a candidate Lyapunov function shown in the image.
Discuss the positive definiteness of V (x, x_dot).
Derive the Lyapunov rate of this system (i.e., V_dot ), and discuss the stability property of thesystem based on the information we gain from ̇V_dot .
A 3-phase, 6-pole induction motor is con-
nected to a 60 Hz supply. The voltage in-
duced in the rotor bars is 4 V when the ro-
tor is locked. If the motor turns in the same
direction as the flux, calculate the approxi-
mate voltage induced and its frequency:
a. At 300 r/min
b. At 1000 r/min
c. At 1500 r/min
