A force of 50 N is applied to the handle of the door as shown. Determine the projection of the moment of this force about the hinged axis z. Neglect the size of the doorknob. Suggestion: Use a scaler analysis.
| A. | Mz = 15.9 N-m |
| B. | Mz = -15.9 N-m |
| C. | Mz = -27.6 N-m |
| D. | Mz = 27.6 N-m |

The wind has blown sand over a platform such that the intensity of load can be approximated by the function
. Simplify this distributed loading to a single concentrated force and specify the magnitude and location of the force measured from A.
| A. | R = 1250 N, x = 6.67 m |
| B. | R = 2500 N, x = 6.67 m |
| C. | R = 1250 N, x = 8 m |
| D. | R = 2500 N, x = 8 m |
