A powered winding drum is tested in four separate cable-recovery trials. In each trial, the pull remains constant and the cable moves in the direction of the pull.
| Trial | Pull / N | Cable displacement / m |
|---|---|---|
| A | 128 | 16 |
| B | 175 | 12 |
| C | 92 | 24 |
| D | 255 | 8.4 |
The drum does a different amount of work in each trial. Determine the trial with the minimum work done. Show your working.
