I'm working on a project for a software engineering class & I figured I'd do something 4x4 related since I get to pick & this is what I'm thinking. I need a list of all wheeling related formulas like how to figure gear ratios, approach angles, center of gravity,... stuff like that. I've searched google & most of the stuff I found was engine stroke & volume stuff, not really looking for that. What I'm planning is to write a program that would have a bunch of different calculators in it & you just pick the one you need & enter in the necessary info. This still has to be approved by my teacher & my group(lazy sobs that won't ever show up) but that shouldn't be a problem since I'm the group leader.
