Velocity Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
Velocity Ratio = No. of Teeth on Driven/No. of Teeth on Driver
i = Tdriven/Tdriver
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.
No. of Teeth on Driven - No. of teeth on driven is the count of number of teeth on the driver.
No. of Teeth on Driver - No. of teeth on driver is the count of number of teeth on the driver.
STEP 1: Convert Input(s) to Base Unit
No. of Teeth on Driven: 15 --> No Conversion Required
No. of Teeth on Driver: 20 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
i = Tdriven/Tdriver --> 15/20
Evaluating ... ...
i = 0.75
STEP 3: Convert Result to Output's Unit
0.75 --> No Conversion Required
FINAL ANSWER
0.75 <-- Velocity Ratio

FAQ

What is Velocity Ratio?
Velocity ratio is the ratio of the speed of the driver to the speed of the driven or follower(or) the ratio of speeds of any pair of gears in mesh is the inverse of their number of teeth and is represented as i = Tdriven/Tdriver or Velocity Ratio = No. of Teeth on Driven/No. of Teeth on Driver. No. of teeth on driven is the count of number of teeth on the driver & No. of teeth on driver is the count of number of teeth on the driver.
How to calculate Velocity Ratio?
Velocity ratio is the ratio of the speed of the driver to the speed of the driven or follower(or) the ratio of speeds of any pair of gears in mesh is the inverse of their number of teeth is calculated using Velocity Ratio = No. of Teeth on Driven/No. of Teeth on Driver. To calculate Velocity Ratio, you need No. of Teeth on Driven (Tdriven) & No. of Teeth on Driver (Tdriver). With our tool, you need to enter the respective value for No. of Teeth on Driven & No. of Teeth on Driver and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
