Engineering Mechanics Practice Test 9

1. We sometimes use the moment caused by the force so as to determine the moment of inertia of the body. The moment is the cross product of which two vectors?

2. 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)?

3. What is the radius of the Mohr circle of the structure given below?

4. The tendency of rotation of the body along with axis is also called ___________ As used for the construction of the Mohr circle.

5. Composite materials are of no use for any engineers.

6. In the calculations of the moment of inertia of the area about an inclined axis, we have some transformation done. They are:

7. There is parallel axis theorem for the area, and it is can be used to determine the moment of inertia of an area about inclined axis.

8. The parallel axis theorem can add any angle varied moment of inertias to give the perpendicular moment of inertia and it can be used in the determination of the moment of inertia about inclined axis.

9. In the calculations of the moment of inertia of the area about an inclined axis, we have some transformation done. They are:

10. The distance in the parallel axis theorem is multiplied by ___________
