Three rods are arranged in the form of an equilateral triangle. Calculate the M.I. about an axis passing through the geometrical centre and perpendicular to the plane of the triangle (Assume that mass and length of each rod is M and L respectively).

Three identical rods are joined together to form an equilateral triangle frame. Its radius of gyration about an axis passing through a corner and perpendicular to the plane of the triangle is.

A rod of mass M, length L is bent in the form of hexagon. Then MOI about axis passing through geometric centre and perpendicular to plane of body will be

Three identical rods, each of length L , are joined to form a rigid equilateral triangle. Its radius of gyration about an axis passing thorugh a corner and perpendicular to plane of triangle is

Three idential rods, each of length L , are joined to from a rigid equilateral triangle. Its radius of gtration about an axis passing thorugh a corner and perpendicular to plane of triangle is

The M.I. of thin uniform rod of mass 'M' and length 'l' about an axis passing through its centre and perpendicular to its length is

Three identical uniform thin metal rods form the three sides of an equilateral triangle. If the moment of inertia of the system of these three rods about an axis passing through the centroid of the triangle and perpendicular to the plane of the triangle is 'n' times the moment of inertia of one rod separately about an axis passing through the centre of the rod and perpendicular to its length, the value of 'n' is
