Linear force on lead screw drive

[Nico33]

I have a lead screw drive. The stepper motor puts out 280 oz-in of torque. Its attached to a 1/2 inch dia., .200" pitch, 2 start lead screw. There is a plate that's attached to the screw that moves back and forth along the screw. How much force can that metal plate exert in a linear motion?

This sounds like homework, have you done any work to try and solve this problem? Even something as simple as an internet search?

It's not homework. It's for my job. It's a problem we're trying to solve. I've been doing online searches for quite some time now.

Apparently, you have been searching with the wrong subject title:
For a listing of multiple sites addressing your application Google "linear drive lead screw design equations" and for one specific site addressing your design go to:

That is very helpful, thank you. Maybe I was wording it incorrectly when I was searching.

I understand, just be persistent and imaginative in rewording your searchs. Sometimes, when I search I have to restate my search description several times in order to find what I looking for; and, even that does not reveal information that I am sure is out there somewhere.
