This is a continuation of Prob. 13–45. Here, you are asked to find the forces exerted by gears 2 and 3 on their shafts as shown in part b. Gear 2 rotates clockwise about the y axis. Gear 3 is an idler.

Prob. 13–45, The gears in the two trains shown in the figure have a normal diametral pitch of 5 teeth/in, a normal pressure angle of 20◦, and a 30◦ helix angle. For both gear trains the transmitted load is 800 lbf. In part a the pinion rotates counterclockwise about the y axis.

Find the force exerted by each gear in part a on its shaft.
