![Q6:- A gearbox is to be arranged to give four speeds in an approximate
geometrical progression, one of which is to the direct shaft. The driving
shaft transmits 40 hp at 3000 rpm. The speed of the intermediate shaft
is approximately 2000 rpm and the speed of the lowest gear is
approximately 600 rpm. The distance between the driving and the
intermediate shafts is 1 ft and all the teeth are of module 5 mm.
Calculate :- (a) the necessary number of teeth for each gear and (b) the
resisting torque on the driven shaft and the torque on the frame of the
gearbox in the lowest gear, neglect the friction loss.
