A gear train is composed of four helical gears with the three shaft axes in a single plane, as shown in the figure. The gears have a normal pressure angle of 20 and a 30 helix angle. Gear 2 is the driver and is rotating counterclockwise as viewed from the top. Shaft bis an idler and the transmitted load from gear 2 to gear 3 is 750 ibf, Both the gears on shaft b have a normal diametral pitch of 8 teeth/in and have 54 teeth and 14 teeth, respectively. Find the magnitude of the tangential, radial, and axial forces exerted by gear 4 on shaft b. ook Hint Priet Problem 13-47 erences RH The magnitude of tangential force exerted by gear 4 on shaft bis Ibf The magnitude of radial force exerted by gear 4 on shaft bis Ibt The magnitude of axial force exerted by gear 4 on shaft bis Ibf.
