|
|
1. Piston X moves backwards and forwards, what type of motion is this? |
|
| 2. What is a movable pivot? | |
| 3. Place labels on the diagram to show the position of two moving pivots. | |
|
4. Engineers have found that as the system rotates there is a problem with the mechanism. In the space below describe the problem. |
|
| 5. In the space below draw a solution to the problem. | |
|
6. Internal combustion engines are linked to pollution. What type of pollution do they create. |
