Vedclass · Answer

(B) The tension $T$ in the string of a simple pendulum at an angle $	heta$ with the vertical is given by $T = mg \cos 	heta + \frac{mv^2}{l}$.At the mean position,$	heta = 0^{\circ}$,so $\cos 	heta = 1$ (maximum value).Also,the velocity $v$ is maximum at the mean position.Since both terms $mg \cos 	heta$ and $\frac{mv^2}{l}$ are at their maximum values at the mean position,the total tension $T$ is maximum at the mean position.

At which position in the string of a simple pendulum is the tension maximum?
