Problem 16DQ

At what point in the motion of a simple pendulum is the string tension greatest? Least? In each case give the reasoning behind your answer.

Step-by-Step Solution:

Solution 16DQ Step 1: The simple pendulum diagram as shown in below: Step 2: The tension in the string provides the force for circular motion.if is the angle string which makes with vertical then the component of weight which is oppositely directed to tension is mg cos .if lbe the length of string then we have the equation for circular motion is given by 2 mv /l = T mg cos Rearranging above equation we get T = mv /l + mg cos Hence the maximum value of T occurs when v and cos are maximum.
