The actuator shown in the figure is driven by a force of 15 lb applied to the plunger. The model should be studied when the actuator piston faces a 500 lb/in resistance from the actuator casing. The base of the mechanism sits on a thick sheet of rubber characterized by 1000 (lbs/in)/in2 stiffness.

In this lesson, you learn the following:
- Defining different types of pins
- Defining elastic support
- Running frequency analysis and listing the actuator's natural frequencies
