1] Belt material selection

(Leather, $\mathrm{E}=90 \mathrm{MPa}, \quad [\sigma]=7 \mathrm{MPa}, \sigma^{-1}=9$ to 10 $\mathrm{MPa}$ and $\rho = \frac{1400 \mathrm{kg}}{\mathrm{m}^{3}}$ and $\mu=0.25$

2] Belt section selection (as shown in the figure)

For given or assumed application determine service factor (SF) $\quad$ PSG-7.69

Based on design power $P_d = SF × P_m$ …
