Задача 10088.

Determine the moment of inertia of the wire of an equilateral triangle with a side of 10 cm with respect to: 1) an axis lying in a plane passing through the triangle and its vertex parallel to the side opposite this vertex; 2) the axis of which coincides with one of the sides of the triangle. M = mass of the triangle 12 g uniformly distributed along the length of the wire.
