The moment of inertia of the pendulum is determined as 0.0025 kgm².
What is moment of inertia?
The moment of inertia of an object is defined as a measurement the rotation of the object around a fixed axis.
The pendulum can be modelled as a circular disk and the moment of inertia is calculated as follows;
I = ¹/₂Mr²
where;
- M is mass of the pendulum
- r is the radius of the pendulum
- I is the moment of inertia of the pendulum
Substitute the given parameters and solve for the moment of inertia of the pendulum.
I = 0.5 X 0.5 kg x (0.1)²
I = 0.0025 kgm²
Thus, the moment of inertia of the pendulum is determined as 0.0025 kgm².
