Question

Find the moment of inertia of a solid cylinder of diameter 1 m and mass 60 kg about its axis.
Options
A 30 kg·m²
B 7.5 kg·m²
Correct Answer
C 15.0 kg·m²
D 3.0 kg·m²
Correct Answer

Option B is the correct answer.

Detailed Explanation

Radius r = 0.5 m. For solid cylinder about axis, I = ½MR² = ½ × 60 × (0.5)² = 30 × 0.25 = 7.5 kg·m².

Hint

I_solid cylinder = ½MR².
