2.7 Shrinkage
- Theoretical value: (a=35, : Maximum Shrinkage Strain Ratio)
- The process of finding 'a'

3. Finding 'a'=66.39
■ Result discussion
Because we used a broken gage, we're choosing remains of 2 gages.
The greatest error in shrinkage test was that we couldn't get a expected strain; because we had a mistake not exactly attaching gages.
2.8 Creep
