Engineering Mechanics Practice Test 2

1. The ___________ forces do not cause the rotation.

2. Determine the magnitude of the moment of the force about the axis PQ.

3. Determine the resultant moment caused by the forces in vector

4. The forces of the collinear system and the couple can’t be simplified together as one is the cause and the other is the effect.

5. In the calculation of the moment of the force about the axis, the cross product table, i.e. the 3X3 matrix which is made for doing the cross product having 3 rows, contains three elements. Which are they from top to bottom?

6. Coplanar forces are not easily simplified in the simplification of the force and couple system.

7. If a force applied at any point in its line of action and is still creating the same moment about any fixed point say P, then the force is said to be______________

8. Which of the following is correct? (For A representing the vector representation of the axis of rotation, r the radius vector and F the force vector)

9. The resultant force is equal to the _______ of all the forces.

10. Determine the moment about the point S.
