A wheel of mass 8 kg has moment of inertia equals to `0.5 "kg-m"^(2)`. Determine its radius of gyration.

Explanation

To determine the radius of gyration of the wheel, we can follow these steps:

### Step 1: Understand the relationship between moment of inertia, mass, and radius of gyration.
The moment of inertia (I) of a body can be expressed in terms of its mass (m) and radius of gyration (k) using the formula:
\[ I = m \cdot k^2 \]

### Step 2: Rearrange the formula to solve for the radius of gyration (k).
To find the radius of gyration, we can rearrange the formula:
