Problem 3: Find the natural frequency of the system shown in Figure 3. Problem 4: In the mechanical system shown in Figure 4, assume that the rod is massless, perfectly rigid, and pivoted at point P. The displacement x is measured from the equilibrium position. Assuming that x is small, that the weight mg at the end of the rod is 5 N, and that the spring constant k is 400 N/m, find the natural frequency of the system. 2a...
THE SPRING FORCE AND SIMPLE HARMONIC MOTION To measure and study various characteristics of a mass/spring system, including the spring constant and the dependence of the oscillation frequency on the amplitude of oscillation. i) You will measure the spring constant using two different methods: static and dynamic. ii) You will investigate the dependence of frequency on the amplitude of oscillations. 1. Write the equation that relates the applied force (not the spring force) on a spring to the displacement from...
A mass on a spring has an angular oscillation frequency of 2.81 rad/s. The mass has a maximum displacement (when t = 0 s) of 0.232 m. If the spring constant is 25 N/m, what is the potential energy stored in the mass-spring system when t = 1.42 s? How long will it take the mass to pass through the equilibrium position for the 7th time?

A mass m hangs on the end of a cord around a pulley of radius a

spring remains essentially
horizontal and neglect friction so that the conservation of energy
