Q2. Figure Q2 shows a simple gear train. At the instant shown, a force F = 1100 N is applied at one end of a 0.175 m long lever, perpendicular to the length of the lever. The other end of the lever is attached to shaft 1, and so the lever turns shaft 1. Gear A is attached to shaft 1 and has 48 teeth. Gear A is meshed with gear B, which has 16 teeth. a) What is the gear ratio from gear A to gear B? The efficiency of power transmission between the two gears is 70%. The moment of inertia of shaft 1, including the lever and gear A is 1.05 kgm² and the moment of inertia of gear B is 0.15 kgm². The frictional torque on shaft 1 is 0.2 Nm and the frictional torque on gear B is 0.7 Nm. If, at the instant show, the lever is moving downwards with a velocity of 1.4 m/s and an acceleration of 0.15 m/s², determine: b) the torque transmitted to gear A. c) the torque transmitted to gear B. d) the power transmitted to gear B. 1100 N 1.4 m/s 0.15 m/s² Lever 0.175 m Gear A Gear B

Q2. A specially designed wrench is used to twist a circular shaft by means of a square key that fits into slots (or keyways) in the shaft and wrench, as shown in the figure on the next page. The shaft has diameter d, the key has a square cross section of dimensions b x b, and the length of the key is c. The key fits half into the wrench and half into the shaft (i.e., the keyways have a depth equal to b/2). Derive a formula for the average shear stress Twg in the key when a load P is applied at distance L from the center of the shaft. Draw the free body diagram.
