Consider a uniform horizontal solid cylinder of mass \(10 \mathrm{~kg}\) such that its length is 9 times its radius. Let the radius be \(40 \mathrm{~cm}\). Calculate the moment of inertia of the cylinder about a line passing through its edge and perpendicular to its axis.
- A \(21.3 \mathrm{~kg}-\mathrm{m}^2\)
- B \(18.7 \mathrm{~kg}-\mathrm{m}^2\)
- C \(43.6 \mathrm{~kg}-\mathrm{m}^2\)
- D \(10.9 \mathrm{~kg}-\mathrm{m}^2\)
Answer & Solution
Correct Answer
(C) \(43.6 \mathrm{~kg}-\mathrm{m}^2\)
Step-by-step Solution
Detailed explanation
Given, mass of solid cylinder, \(M=10 \mathrm{~kg}\) Radius, \(\begin{aligned} & R=40 \mathrm{~cm}=0.4 \mathrm{~m} \\ & L=9 R=9 \times 0.4=3.6 \mathrm{~m} \end{aligned}\) Moment of inertia of the solid cylinder about the line passing through its centre and perpendicular to its…
