problem 1: (a) design a compound 2-stage reverted gear train as a speed increaser to provide a total speed increase of exactly 48:1. minimize the gearbox size and use 20° pressure angle full depth gears all with the same diametral pitch, and avoid interference. show a simple scaled sketch or drawing of your meshed gears and clearly give the number of teeth on each gear (n2, n3, n4, n5). (b) repeat this with a 22.5° pressure angle. (c) using a diametral pitch of 16, what is the distance between the shafts, d, in cases (a) and (b)?
