*2.4.2 Diameter of driven pulley*

The velocity of driven pulley is increased by 1.4 times (**Figure 10**):

$$\text{velocity ratio} = \frac{\text{N}\_2}{\text{N}\_1} = \text{1.4} \tag{15}$$

Diameter of shaft of driven pulley = 20.00 mm.

Length of collar of driver pulley = 14 mm. Length of collar of driven pulley = 14 mm. Diameter of tap = 4 mm (for both).

Diameter of bore of collar of driver pulley = 20 mm. Diameter of bore of collar of driven pulley = 20.02.
