From this paper

A helical gear has a transverse diametric pitch of 12, a transverse pressure angle of 14 1 2 ◦ , 28 teeth, a face width of 1.25 in, and a helix angle of 30 ◦. Compute the transverse circular pitch, normal circular pitch, normal diametric pitch, axial pitch, pitch diameter, and the normal pressure angle. Compute the number of axial pitches in the face width. (24 marks (4 marks each))
