Velocity Ratio of Simple Screw Jack Solution

STEP 0: Pre-Calculation Summary

Formula Used

Velocity Ratio = (2*pi*Length of Lever Arm)/Pitch
V_i = (2*pi*l)/P_s
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

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.
Length of Lever Arm - (Measured in Meter) - Length of lever arm is the is the distance measured from one end of lever to other end.
Pitch - (Measured in Meter) - Pitch is the distance between screw threads and is commonly used with inch sized products and specified as threads per inch.

STEP 1: Convert Input(s) to Base Unit

Length of Lever Arm: 12 Meter --> 12 Meter No Conversion Required
Pitch: 14 Meter --> 14 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_i = (2*pi*l)/P_s --> (2*pi*12)/14

Evaluating ... ...

V_i = 5.38558740615393
