## A revision must satisfy both clearance limits

Fictional extension: clearance must now remain between 0.3 and 0.8 mm inclusive. The tab remains 19.5 ± 0.1 mm. Use the same one-dimensional worst-case model.

### Two proposed opening dimensions

| Revision | Opening | Minimum clearance | Maximum clearance |
| --- | --- | --- | --- |
| A: tighter tolerance | 20.0 ± 0.1 mm | Calculate | Calculate |
| B: larger nominal size | 20.1 ± 0.2 mm | Calculate | Calculate |

## Your turn

Which revision satisfies both supplied limits? What question remains before choosing it for a physical part?

## Your answer

[Write your approach here.]

## For your own application

Put every relevant requirement beside the revision, rather than checking only the one that failed first.
