Answer 2

Step-by-step explanation:

Given:-

Three identical thin rods

Mass (m)

Length l of an equilateral trianlge.

To find :- Momentum and inertia of

system

MOI of system=>lAC+lAB +lBC

IAB =0 it is at the axis

IBC=1/3m(1eff)2

1/3m(1sin60)2

=1/3ml2×3/4

MOI =0+ml2/4+ml2/4

=>ml2/2

Hence ,the moment of inertia of the trianlge about one of its side=ml^2

Ans=option 2.
