? 0 0? 79%, 8:26 AM XQuestion The below figure shows a simplified version of the transmission electrical motor which is delivering a torque T-3000 lb.in to the transmission, and the transmission is in low gear with a ratio R- 2.778 (For this problem consider R to be a torque ratio. Tout/Tin. To the degree that friction losses are present, the speed ratio, vin/vout, would have to be slightly greater.) The other three portions of the figure show the major parts of the transmission. Gear diameters are given in the figure Input gear A rotates at engine speed and drives countershaft gear B. Countershaft gear C meshes with main shaft output gear D. (The construction of the main shaft is such that the input and output ends rotate about a common axis, but the two halves are free to rotate at different speeds.) The main shaft is supported in the housing by bearings I and II. Similarly, the countershaft is supported by bearings III and IV. Determine all loads acting on the components shown in Figures b, c, and d, thus representing them as free bodies in equilibri Suppose that the forces acting between mating gear teeth are tangential.
