Figure P16.10 shows a double-reduction helical-gear arrangement used in an industrial machine. Modules in the normal plane are 3.5 and 5 mm for the high- and lows peed gears, respectively. The helix angle of the high-speed gears is 0.44 rad.
(a) What is the total speed reduction provided by the four gears?
(b) What is the helix angle of the low-speed gears?
(c) If the low-speed gears are replaced by 24- and 34-tooth gears of the same modulus, what helix angle must they have?
