Helix angle the helix angle. The efficiency can be plotted versus the helix angle for a constant friction, as shown in the adjacent diagram. The maximum efficiency is a helix angle between 40 and 45 degrees, however a reasonable efficiency is achieved above 15°. Due to difficulties in forming the thread, helix angle greater than 30° are rarely used. Moreover, above 30° the friction angle becomes smaller than the helix angle and the nut is no longer self-locking and the mechanical advantage disappears. In helical and worm gears, the helix angle denotes the standard pitch circle unless otherwise specified. Application of the
Less Than Jake band programs. On June 20, 2011, the band released an EP, entitled "Greetings from Less Than Jake", which was made available on the group's online store and was sold on Warped Tour 2011 as well. On February 16, 2012 Less Than Jake released a follow-up EP, entitled "Seasons Greetings from Less Than Jake". The band announced both EP's would be re-released, with 2 unreleased songs, as part of a new album called "Greetings and Salutations from Less Than Jake", released in October 2012 through Fat Wreck Chords, who had released "Borders and Boundaries".
