NOTES:
Shape 34: Where the overall dimension of the bob is critical
use shape 37.
Shape 35: Do not use this shape where the overall dimension
of either bob is critical
Shapes 37 & 51: The formulae is approximate.
Shapes 42 & 49: The formulae for 'L' should not be
used for angles with horizontal exceeding 45°
All other shapes are Shape 99 and require a fully dimensioned
sketch
