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
Larger than Life (film) Larger than Life (film) Larger Than Life is a 1996 American comedy film starring Bill Murray, and directed by Howard Franklin. It was produced and co-written by Pen Densham. The film was financially and critically unsuccessful. The film opens at a convention of recliner salesmen, where Jack Corcoran (Bill Murray) gives a motivational speech based on his book "Get Over It". Jack shares the example of his father dying before he was born as a difficult circumstance that must be overcome to succeed. At Jack's engagement party, his agent (Jeremy Piven) updates him on all of his upcoming speaking engagements,
