We use sometimes the measures to know the direction of mass moment of inertia. It is done by right handed coordinate system. Which is right about it for the composite bodies (consider the mentioned axis to be positive)? |
| A. | Thumb is z-axis, fingers curled from x-axis to y-axis |
| B. | Thumb is x-axis, fingers curled from z-axis to y-axis |
| C. | Thumb is y-axis, fingers curled from x-axis to z-axis |
| D. | Thumb is z-axis, fingers curled from y-axis to x-axis |
| E. | ?a) Thumb is z-axis, fingers curled from x-axis to y-axisb) Thumb is x-axis, fingers curled from z-axis to y-axisc) Thumb is y-axis, fingers curled from x-axis to z-axisd) Thumb is z-axis, fingers curled from y-axis to x-axis |
| Answer» B. Thumb is x-axis, fingers curled from z-axis to y-axis | |

If any external force also is applied on the distributed loading on which the mass moment of inertia is to be determined on the composite body then? |
| A. | The net force will act at the centroid of the structure only |
| B. | The net load will not be formed as all the forces will be cancelled |
| C. | The net force will act on the base of the loading horizontally |
| D. | The net force will not be considered, there would be a net force of the distribution, and rest will be the external forces |
