Branches that are more perpendicular to a trunk are stronger than those that are more parallel. Ideally, a fork should be 45 to 90 degrees.
|Weak Verses Strong Branch Angles|
Watch this video demonstration showing the different results of downward pressure on two branches at different angles.
Notice below how the branch on the right broke and only split one to two inches while the one on the left split six to eight inches and the split nearly removed half of the main branch.
When choosing which branch to cut and which to leave, consider the angle at which the branch is in relation to the trunk.
