Website Info for force

I am a little slow with my phyics and force from ballscrews or
leadscrews, is there a web site that will give formulas for the
following:
1)force from leadscrew per oz/in of torque
2)acceleration from the force applied
3)general design info using leadscrews

If there isn't one could someone send me what I a, looking for and I
will post it on a website for others to use.

Thanks
Ian
