Question

The pendulum is modeled as a rod of length \( l \) and uniformly distributed mass \( m \). The pendulum pivot is a horizontal distance \( \Delta \) from the vertical spin axis. Let \( \omega \) represent the angular rate of the system about vertical and let \( \theta \) represent the pendulum angle. ( \( \theta \) is zero when the pendulum hangs down; see Figure 1.) Figure 1: Whirling planar pendulum.

a-simple-pendulum-consists-of-a-mass-m-swinging-at-the-end-of-a-rod-or-wire-of-negligible-mass-the-f

A simple pendulum consists of a mass $m$ swinging at the end of a rod or wire of negligible mass. The figure shows a simple pendulum of length $L$. The angular displacement $\theta$ at time $t$ is given by a trigonometric expression: $$\theta(t)=A \sin (\omega t+\phi)$$ where $A, \omega, \phi$ are constants. (FIGURE CAN'T COPY) (a) Show that the function $\theta$ satisfies the equation $$\frac{d^{2} \theta}{d t^{2}}+\omega^{2} \theta=0$$ (Except for notation, this is the equation of Exercise $71 .$) (b) Show that $\theta$ can be written in the form $$\theta(t)=A \sin \omega t+B \cos \omega t$$ where $A, B, \omega$ are constants.

The compound pendulum is composed of a uniform slender rod of length $l$ and mass $2 m$ to which is fastened a uniform disk of diameter $l / 2$ and mass $m .$ The body pivots freely about a horizontal axis through $O .$ If the pendulum has a clockwise angular velocity of 3 rad/s when $\theta=0$ at time $t=0,$ determine the time $t$ at which the pendulum passes the position $\theta=90^{\circ} .$ The pendulum length $l=0.8 \mathrm{m}$
