The period of a simple pendulum with large angle is presented; a comparison has been carried out between the analytical solution and the numerical integration results. A simple pendulum is defined to have an object that has a small mass, also known as the pendulum bob, which is suspended from a light wire or string, such as shown in Figure 16.13.

Simple Harmonic Motion Chapter Problems - Weebly /FontDescriptor 11 0 R If the length of a pendulum is precisely known, it can actually be used to measure the acceleration due to gravity. Compare it to the equation for a straight line. Set up a graph of period squared vs. length and fit the data to a straight line. g Solution: The period of a simple pendulum is related to its length $\ell$ by the following formula \[T=2\pi\sqrt{\frac{\ell}{g}}\] Here, we wish $T_2=3T_1$, after some manipulations we get \begin{align*} T_2&=3T_1\\\\ 2\pi\sqrt{\frac{\ell_2}{g}} &=3\times 2\pi\sqrt{\frac{\ell_1}{g}}\\\\ \sqrt{\ell_2}&=3\sqrt{\ell_1}\\\\\Rightarrow \ell_2&=9\ell_1 \end{align*} In the last equality, we squared both sides.
