Trèteaux Angles: PSBa-DP
PSBa-DP = Prism Footprint Saw Blade Bevel Angle Along side of Hip Rafter on DP Side at Foot of Hip Rafter
Hip-Valley Roof Ratios Angle Formulas
- PSBa-DP = arctan( sin(R8) × tan(90 - Jack Rafter Side Cut Angle))
- PSBa-DP = arctan( sin(R8) × tan(90 - P2m))
The Trèteaux Angles Formulas for Hip Rafters Rotated into the Roof Surface Plane were developed by Sim Ayers and Joe Bartok.
