Spur gear Lewis bending stress

Calculates simplified, non-code contact stress with a user-entered elastic coefficient.

Calculates tangential, radial, and normal mesh forces from torque, pitch diameter, and pressure angle.

Calculates radial force from tangential force and pressure angle.

Calculates bevel gear pitch angles for 90-degree intersecting shafts.

Calculates base circle diameter from pitch diameter and pressure angle.

Calculates center distance from two pitch diameters.
