Question

Problem #5) (20 points) Consider the pendulum and spring system of Figure 1. Here the mass of the pendulum rod is negligible. Drive the equation of motion using the Lagrange's formulation. Them linearize the system for small angles and determine the natural frequency. The length of the pendulum is L, the tip mass is M, and the spring stiffness is K.

Step 1

We have the gravitational force acting downwards, given by F_gravity = M * g, where g is the acceleration due to gravity. 2) We also have the tension force in the pendulum rod, which acts towards the center of the circular motion. This tension force can be broken Show more…
