B) Solve Using:
a. Actual Length “x”: 52-5/8 Inches
b. Offset “y”: 25-3/16 Inches
c. End “a”: 34 Inches

1. Enter actual Length as “x”:
oo 0.
52i5/8R X 52-5/8 INCH
2. Enter offset Length as “y”:
25i3/16r Y 25-3/16 INCH
3. Enter Height of “end A” as “a”:
34iÇ4 A34INCH
4. Calculate Centerline Radius, Wrapper Length, Heel Radius,
Throat Radius and Theta:
Ç( RAD 33-13/16 INCH
( WL 60-5/16 INCH
( HEEL 50-13/16 INCH
( THRT 16-13/16 INCH
( THET 25.57682°
“WL”, or the Wrapper, corresponds to the side of the fitting associat-
ed with the offset dimension used for the calculation. The longest
Wrapper corresponds to the side with the largest offset (y).
Caution: When working with a “Change Transitional OGEE
Offset” (Wrapper size transitions from one end to other) the length
of a cheek having a slant length must be adjusted to include
that slant length prior to the calculations above taking place.
