1. The ___________ forces do not cause the rotation/rolling of the body if the rotation is considered in about the axis of the body or the centroid axis of the body.
2. The three force system can also be in the equilibrium if:
3. For the rolling of the body the calculation of the moment of the force about the axis of rolling, 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?
4. In the simplification of the forces applied in the wedges net force acts at the ___________ of the loading body.
5. In the equation A.(rxF) the r is heading from ______________ and ending at _____________
6. Which statement is correct about the vector F acting parallel to the direction of the motion of the rolling body?
7. For the rolling of the body right handed coordinate system means (consider the mentioned axis to be positive)?
8. Dry friction is also called _____________
9. There is the application of the Newton’s third law of motion in the free body diagrams of the friction calculations.
10. As we are using vector math to solve for the unknown forces in the free body diagrams, what is k.i?
11. Rotation is termed as rolling when _______
12. What is not the condition for the equilibrium in free body diagram for calculation of the normal forces?
13. To know the rotations involved in the disks we use right handed coordinate system, in that system which of the following is followed (consider the mentioned axis to be positive)?
14. In rolling, there is the involvement of the vector math. So for rolling 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)
15. We first make equilibrium equations of the sections involving the collar bearings or pivots by considering all the three dimensional forces acting on the section chosen and then the free body diagram is made and solved.
16. A ____________ is a simple machine that is used as to transfer applied forces into much larger forces.
17. The coefficient of friction between the body being slided over the wedge and the wedge surface is generally determined by ____________
18. The normal forces and the forces of friction are collinear.
19. The free body diagram used to explain the theory of dry friction is having ___________ distribution of both the normal forces and frictional surface.
20. Sometimes in the calculations involving the wedges, there are situations when there is a toppling effect on the body. In that, if the net moment of the body is zero that means the distance between the force and the rotational axis is zero.
21. The phenomena of horizontal pull and push explain what?
22. The blocks of heavy weights are being able to lift from the help of the wedges.
23. At what conditions the dry friction occurs between the surfaces in contact?
