Question

For the adjoining diagram, a triangular lamina is shown the correct relation between $I_1$, $I_2$ & $I_3$ is:
($I$ – moment of inertia)

• A. $I_1>I_2$
• B. $I_2>I_1$
• C. $I_3>I_1$
• D. $I_3>I_2$

Answer 1

Answer: (B)

$I_2>I_1$

Answer 2

For triangular lamina
Longest side $→I_{min}$
Smallest side $→I_{max}$
Therefore $I_2>I_1>I_3$

So, the correct option is (B): $I_2>I_1$
