A simple pendulum (mass M and length L) is suspended from a cart of mass m that moves freely along a horizontal track shown at right. You might find it helpful to introduce the dimensionless parameters η-m/M and wo- /g/L. a What are the normal frequencies of small oscillations of the system (0 <1)? b Find and describe the corresponding normal modes of the system. c The cart/pendulum systern is held at rest in the configuration x-0 and θ K...

(c) Figure 1. Mass-Spring-Damper Systems Assume that the displacements of the pendulums are small enough to ensure that the spring is always horizontal (but DO NOT make small angle approximations when writing the EOMS). The pendulum rods are taken to be massless, of length L, and the springs are attached...

Problem 3 (70 pts): Consider the mechanical system in Figure , the so-called "cart pendulum" system. The cart has a moving mass M, and is connected to a linear motor via a flexible coupling with stiffness K and damping B. An inverted pendulum of length1, negligible inertia and mass m is attached to the cart via a rotary actuator. If the pendulum damping coefficient is b, the linear actuator force is F and the rotary actuator torque is t 1)...
A pendulum is attached to the cart that has a mass of 3m and that is free to move along the horizontal direction. From the rest condition, when the lumped mass m of the pendulum makes a 0 angle with the vertical, the pendulum is released. 3m L m Compared to the case in which the cart is fixed (it cannot move), when 0=0°, the speed of the lumped mass at the tip of the pendulum would be smaller.
