1] Belt material selection

(Leather, $\mathrm{E}=80 \mathrm{MPa},\quad [\sigma]=5 M P a, \quad \sigma^{-1}=6 M P a$ and $\rho=\frac{1400 \mathrm{kg}}{\mathrm{m}^{3}}$ and $\mu= 0.3)$

2] Belt and pulley geometry

$i=\frac{d_{2}}{d_{1}}=\frac{n_{1}}{n_{2}} \quad $ ------ without slip

$d_1$ - Diameter of larger pulley (mm)

$n_1$ - Speed of the larger pulley (rpm)

$d_2$ - …
