To be quite honest, I think most folks who managed to pass high school algebra could do engineering math quite easily. But if you asked them what they were doing, or how the equation they're dealing with is derived, they'd be totally lost--which is why engineering is a 4-year (or more) curriculum with math through about 4 semesters worth of calculus and differential equations.


As far as safety factor, what a "good" one is varies by what you're dealing with, and other similar things. If I'm designing something to carry people, I'll use a higher safety factor than if people aren't involved, for example. For an FRC robot, the more critical the system, the higher the FoS should be--to a point. (You probably want somewhere between 1 and overkill, but where overkill is depends a lot on your design, where in the design you're working, what material shape you're using, and how well you made your bumpers this year.)
