1. A simple three-speed transmission is shown. The power flow is as follows: (a) First gear: gear 4 is shifted to mesh with gear 7; power flows through gears 2, 5, 7,4. (b) Second gear: gear 3 is shifted to mesh with gear 6; power flows through gears 2, 5, 6, 3. (c) Third gear: gear 3 is shifted so that the clutch teeth on gear 3 mesh with those on gear 2; a direct drive results. (d) Reverse gear: gear 4 is shifted to mesh with gear 9; power flows through gears 2, 5, 8, 9, 4. An automobile with this transmission has a differential ratio of 3:1 (i.e. drive shaft turns 3 times for each turn of the wheel) and a tire outside diameter of 24". Determine the mechanical advantage of the transmission system (i.e. Omega in/Omega out) and the engine speed for the car under the following conditions: (i) (ii) (!!!) First gear: Third gear: The automobile is traveling at 15 mph. The automobile is traveling at 55 mph. Reverse gear: The automobile is traveling at 3.5 mph.
