Trèteaux Angles: P17a-DP
P17a-DP = Adjacent Side Jack Rafter Miter Angle on DP Side Of Hip Rafter on Face Perpendicular To Roof Surface, Upper Claw Angle
Hip-Valley Roof Ratios Angle Formulas
- P17a-DP = arctan( sin ( Jack Rafter Side Cut Angle ) × tan (Valley Sleeper Saw Blade Bevel Angle ))
- P17a-DP = arctan( sin ( P2a ) × tan (VSB ))
The Trèteaux Angles Formulas for Hip Rafters Rotated into the Roof Surface Plane were developed by Sim Ayers and Joe Bartok.
