| 2009-09-27 | abhishek | 10 | 10 | 10 | 10 | No | sorry ,actually my question is moment of inertia for a rectangle which is parallel to base or perpendicular to base is (breadth*depth^3)/12, but if the rectangle is with some angle to the base, it should be resolved into vertical and horizontal components for which the answer will come with sin and cos angles this is what i want. |
