Answer 2

Given: The screw jack's handle length is 100 mm.

The screw's pitch is 10 mm.

To determine: A basic screw jack's velocity ratio

The formula for calculating the velocity ratio of a simple screw jack is as follows:

$velocity. ratio = \frac{distance. moved. by .ef .fort}{distance. moved. by. load}$

where

R is the length of the arm from the screw's centre.

P refers to the screw's thread pitch.

In the aforementioned formula, we will substitute the given values of R = 100 mm and P = 10 mm.

Ratio of Velocity =

As a result, the simple screw jack's velocity ratio is 62.857.
