Mean comparisons between silver and Norway maple at branch failure.
| Species | Crotch angle* (degree) | Specific gravity (gm/cm3) | Bending stress (newtons/cm2) | Moment (newton meters) |
|---|---|---|---|---|
| Silver maple | 56.7 a | 0.52 a | 2970 a | 3009 a |
| Norway maple | 62.6 a | 0.62 b | 2451 a | 3521 a |
| LSD (0.05) | 8.5 | 0.02 | 881 | 1842 |
Means in columns followed by the same letter are not significantly different.
↵* Mean crotch angles for this study may not be representative over the species since large limbs could not be broken with the technique employed.
