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
360 Degrees of Power selling a mere 27,000 copies. Guest appearances were made by Chuck D ("State of Accommodation: Why Aren't You Angry") and Ice Cube ("Killing Me Softly: Deadly Code of Silence"). One track, "Wild Buck Beer," a fictional commercial for a malt liquor, features an appearance by an anonymous artist under the moniker MC Just Want to Get Paid. 360 Degrees of Power 360 Degrees of Power is the only album by female emcee, author, and activist Sister Souljah, which was released in 1992 on Epic/SME Records. The album was met with criticism, not only for its performances—most of which were angry
