Velocity Ratio in Weston's Differential Pulley Block Solution

STEP 0: Pre-Calculation Summary

Formula Used

Velocity Ratio = (2*Diameter of Larger Pulley)/(Diameter of Larger Pulley-Diameter of Smaller Pulley)
V_i = (2*d_l)/(d_l-d_s)
This formula uses 3 Variables

Variables Used

Velocity Ratio - Velocity Ratio is the distance through which any part of a machine moves to that which the driving part moves during the same time.
Diameter of Larger Pulley - (Measured in Meter) - Diameter of Larger Pulley is the greater value of the diameter between the two pulleys.
Diameter of Smaller Pulley - (Measured in Meter) - Diameter of smaller pulley is the smaller value of diameter between the two pulleys.

STEP 1: Convert Input(s) to Base Unit

Diameter of Larger Pulley: 0.06 Meter --> 0.06 Meter No Conversion Required
