The shaft assembly shown in figure $1$ is driven by a flat belt drive at location $\mathrm{A}$ and drives a flat belt at location $B$. The drive belt pulley diameter is $\mathbf{X}\mathbf{mm}$ and the driven belt pulley diameter is $\mathbf{Ymm}$. The distance between sheaves is $800\mathrm{mm}$, and the distance from each sheave to the nearest bearing is $200\mathrm{mm}$. The belts are horizontal and load the shaft in opposite directions. Determine the size of the shaft using suitable fatigue criteria. Standardize the shaft diameter. Assume suitable material, factor of safety $=2$. Make appropriate assumptions for design. Write all your assumptions clearly. The values of different parameters X,Y,F1,F2,F3,F4 are given in Table 1. Table 2 gives your SRNO. TABLE 3 GIVES FORMAT FOR SOLVING THE PROBLEM. WRITE THE EDITION OF BOOK USED AS STATED IN THIS TABLE. Write all details as per Table 3 , otherwise your assignment will not be evaluated. Solve in SI units only. If iterations are required, make maximum 4 iterations. You can stop earlier if you find the answer in $3^{\text{rd }}$ iteration also. FIGURE 1
