This is untimed educational practice for one applied skill. It is not a clinical, diagnostic, employment, or professionally recognized assessment, it does not produce a score or credential, and for the judgement and safety families it is not a substitute for your employer's own policies, training, or legal duties.
| Item | Choice | Answer |
|---|---|---|
| mechanical-comprehension-applied-s01-q01 | C | The equivalent of 20 kg |
| mechanical-comprehension-applied-s01-q02 | A | 120 rpm, counter-clockwise |
| mechanical-comprehension-applied-s01-q03 | D | The load is between the pivot and the effort |
| mechanical-comprehension-applied-s01-q04 | B | Clockwise, at twice gear A's speed |
| mechanical-comprehension-applied-s01-q05 | A | 4 |
| mechanical-comprehension-applied-s02-q01 | B | It changes the direction of the pull without reducing the force needed |
| mechanical-comprehension-applied-s02-q02 | D | 100 N, and 2 m of rope |
| mechanical-comprehension-applied-s02-q03 | C | 150 N |
| mechanical-comprehension-applied-s02-q04 | A | The effort moves farther than the load, so the total work done is not reduced |
| mechanical-comprehension-applied-s02-q05 | B | 1200 rpm, in the same direction |
| mechanical-comprehension-applied-s03-q01 | D | 1000 N |
| mechanical-comprehension-applied-s03-q02 | C | The depth of water and the density of the liquid |
| mechanical-comprehension-applied-s03-q03 | A | 4 cm |
| mechanical-comprehension-applied-s03-q04 | B | It speeds up |
| mechanical-comprehension-applied-s03-q05 | C | 0.75 |
| mechanical-comprehension-applied-s04-q01 | A | 400 N |
| mechanical-comprehension-applied-s04-q02 | B | Putting rollers underneath so sliding friction becomes rolling friction |
| mechanical-comprehension-applied-s04-q03 | D | The loaded van, because more mass at the same speed means more momentum to remove |
| mechanical-comprehension-applied-s04-q04 | C | To store rotational energy and even out the variation in speed between power strokes |
| mechanical-comprehension-applied-s04-q05 | D | When the vertical line through its centre of gravity falls outside its base of support |
