Asked Nov 6, 2019

A pendulum consisting of a string of length *L* attached to a bob of mass *m* swings in a vertical plane.

(a) When the string is at an angle θ to the vertical, calculate the tangential acceleration of the bob using Σ*F*_{t} = *ma*_{t}. (Use any variable or symbol stated above along with the following as necessary: *g* and θ.) (solved)

a_{t} = gsin(θ)

(b) What is the torque exerted about the pivot point? (Use any variable or symbol stated above along with the following as necessary: *g* and θ.) (unsolved)

Step 1

Given:

Step 2

Step 3

(a)

To calculate the tangential acceleration, we need the requirement of t...
