Questions
Moment of inertia of a square sheet about one side is I. Then the moment of inertia of the same square sheet about one of its diagonals is
detailed solution
Correct option is C
(3)It l be the length of each side, Then I=13 ml2∴ Ix'=IAB− m.a22=13 ml2−14 ma2=112 ma2By perpendicular axis theoremIo=Ixi + Iyj = 2IxAlso Io=IAC+IBO=2IAC∴ IAC=Ix=112 mx2=112 × 3I=14I.Talk to our academic expert!
