    scissor lift calulations

    ipt>
    I've been designing a scissor lift. I found the calculations in engineers edge. I input the numbers and came up with a force result. the result didn't make sense so I wrote the formula in excel and got a quite a different number, almost 1/2 what the engineer edge calculator gave me. the forumla is: F=( W+Wa)/2 Tan (Angle). Where did I go wrong? it seemed pretty straight forward.

    OK, I got it. I didn't know that excel uses radians. I was inputing degs. once I converted my degs to rads it work.

    Ya, that always gets me that excel defaults to radians. I don't think there is a way to defualt otherwise.
