Extracted text: (b) A two-start worm gear that is rotating at 800 rpm drives a 26-tooth worm gear. The worm gear has a pitch diameter of [50] mm and a pitch of [16] mm. If coefficient of friction (u) is 0.06, (i) Determine the helix angle of worm gear. (ii) Determine the speed of gear. (iii) Compute the distance of gear. (iv) Identify the maximum gear efficiency of this transmission system.
