Trèteaux Angles: P14a-DP
P14a-DP = Adjacent Side Purlin Rafter Miter Angle on DP Side Of Hip Rafter on Face Perpendicular To Roof Surface, Upper Claw Angle
Hip-Valley Roof Ratios Angle Formulas
- P14a-DP = arctan( cos ( Jack Rafter side Cut Angle ) ÷ tan ( 90 - Valley Sleeper Saw Blade Bevel Angle ))
- P14a-DP = arctan( cos (P2a ) ÷ tan (90 - VSB ))
- P14a-DP = arctan( tan(P17a ) ÷ tan (P2a ))
The Trèteaux Angles Formulas for Hip Rafters Rotated into the Roof Surface Plane were developed by Sim Ayers and Joe Bartok.
