FWIW they said a higher angle stem, not longer stem.
No. The shape or angularity of the lever doesn't matter. All that matters is the force vector and the straight line distance from the pivot point and the force itself. the lever (stem etc) can be I, L, S or even U shaped.
Mathematically it is the cross product of the force vector and the vector from the pivot point to where the force is applied. I hate posting a diagram on a site like this but maybe is will resonate with some.
