The figure below shows a two-stage helical gear set. Pinion 2, which is in the converter position, transfers a certain rotation moment from the shaft to gear 3 in the first stage by rotating in the direction of the clock in the front view (or in the Z direction) shown in the figure. on shaft B, the pinion gear No. 4 is positioned with gear No. 3, which receives and/or transmits the drive from different gears. The number 4 Pinion in the second stage drives the number 5 gear, converting the input moment in the system to the output moment and providing movement transfer. Answer the figure in the table as follows by determining the direction of rotation of Gears 3, 4 and 5 and the Helix direction of each gear when looking at the left side view of the figure from the left (i.e. from the-z direction).Also, briefly explain how the concept of a module in Gears is determined by showing the basic dimensions on a tooth form and what the main law of gears refers to by drawing a figure.
