Which of the following is true for the bearing s body? |
| A. | Total moment of various forces acting on the body is the vector sum of all moments in 3D |
| B. | Total moment of various forces acting on the body is the algebraic sum of all moments in 3D |
| C. | Total moment of various forces acting on the body is always zero in any dimension |
| D. | Total moment of various forces acting on the body is the vector sum of all moments which is perpendicular to each other forces whatever be the dimensions |
| Answer» B. Total moment of various forces acting on the body is the algebraic sum of all moments in 3D | |

The doors are having hinges to support them. This hinge is too a type of bearing or is a Device which is using the effect like bearing to support. So, if you are opening the door, then the force you apply is greater if you open it from the part closer to the hinges. |
| A. | True |
| B. | False |
| Answer» B. False | |
| 3. |
Which of the following is true for the determination of the rotational effect of the bearings? |
| A. | If we are considering the clockwise direction to be positive then the rotation along the counter clockwise direction is negative |
| B. | If we are considering the clockwise direction to be negative then the rotation along the counter clockwise direction is also negative as no such assumptions can be taken |
| C. | If we are considering the clockwise direction to be positive then the rotation along the counter clockwise direction is also positive as no such assumptions can be taken |
| D. | If we are considering the clockwise direction to be negative then the rotation along the counter clockwise direction is neither positive nor negative as we only pre assumed the clockwise direction |
| Answer» B. If we are considering the clockwise direction to be negative then the rotation along the counter clockwise direction is also negative as no such assumptions can be taken | |
