• (A) Try to calculate the moment of inertia of a thin plate, in the shape of a right triangle, about an axis as shown in Figure (a)-(d). If m represents the mass of the triangle and dm mass of small mass element (strip), do the calculation for all four ways (a)-(d). (B) If I represent the moment of inertia calculated in part (A), calculate the inertia ICM that represent the moment of inertia of the triangle about an axis through the center of mass and parallel to side h. (C): Have you succeeded to calculate I in all four cases? If failed in any one of the parts, why? Note: The center of mass of the triangle is two thirds of the way along the length L, from the corner toward the side of height h.
