Question

A uniform solid sphere has mass m= 7 kg and radius r= 0. 4 m. What is its moment of inertia about an axis tangent to its surface?

Answer 1

The moment of inertia of a uniform solid sphere is equal to 0.448 $kgm^2$.

Given the following data:

Mass of sphere = 7 kg.

Radius of sphere = 0.4 meter.

How to calculate moment of inertia.

Mathematically, the moment of inertia of a solid sphere is given by this formula:

$I=\frac{2}{5} mr^2$

Where:

• I is the moment of inertia.

• m is the mass.

• r is the radius.

Substituting the given parameters into the formula, we have;

$I=\frac{2}{5} \times 7 \times 0.4^2\\\\I=2.8 \times 0.16$

I = 0.448 $kgm^2$.
