Four identical rods are joined end to end to form a square. The mass of each rod is `M`. The moment of inertia of the square about the median line is

A square frame is made rods each of mass m and length l . The moment of inertia of the square about its face diagonal is

Four thin uniform rods each of length L and mass m are joined to form a square . The moment of inertia of square about an axis along its one diagonal is

Four thin metal rods, each of mass M and length L , are welded to form a square ABCD as shown in figure. The moment of inertia of composite structure about a line which bisects rods AB and CD is

Four identical rods of same material are joined end to end to form a square. If the temperature difference between the ends of a diagonal is 100^(@)C , then the temperature difference between the ends of other diagonal will be

Two uiform identical rods AB and CD each of mass M and length L are joined to form a cross as a shown in fig.find the moment of inertia of the cross about a bisector as shown dotted in the figure. .
