The velocity ratio of simple screw jack when length of handle is 100mm and pitch of screw is 10 mm
Answers
Given:
The length of handle of the screw jack = 100 mm
The pitch of the screw = 10 mm
To find:
The velocity ratio of a simple screw jack
Solution:
The formula to find the velocity ratio of a simple screw jack is given as,
where
R = length of the arm from the center of the screw
P = pitch of the thread of the screw
Now, we will substitute the given values of R = 100 mm and P = 10 mm in the above formula,
Velocity Ratio =
Thus, the velocity ratio of simple screw jack is 62.857.

Solution:
The formula to find the velocity ratio of a simple screw jack is given as,
\boxed{Velocity\:Ratio\:=\:\frac{distance\:moved\:by\:effort}{distance\:moved\:by\:load}\:=\:\frac{2\:\pi\:R}{P} }

where
R = length of the arm from the center of the screw
P = pitch of the thread of the screw
Now, we will substitute the given values of R = 100 mm and P = 10 mm in the above formula,
Velocity Ratio = \frac{2\:\times\:\frac{22}{7}\:\times\:100 }{10} = \frac{628.57}{10} = \bold{62.857}
