What happens to the rotational inertia of a simple pendulum when the mass of the bob is doubled and the length of the pendulum is halved? (See Figure 12.6.)
Resulting rotational inertia.
Answer to Problem 42A
The resulting rotational inertia is halved that is
Explanation of Solution
Given:
Mass of the bob is doubled.
Length of the pendulum is halved.
Formula Used:
The rotational inertia of simple pendulum is given as,
Where,
Calculation:
New mass of bob is,
New length of pendulum is,
So resulting rotational inertia is,
Conclusion:
Therefore, the resulting rotational inertia of simple pendulum is halved that is
