Just a simple 3 -D statics problem worked using Mathcad vectors. If you can get students comfortable with vector arithmetic this form of the solution can save time and confusion.
open prime 2, go to getting started, go to migration guide, follow the instructions. Warning - the result will probably not be pretty, I use "insert math region" alot in my docs and prime 2 does not accept it. You would be better to leave it in 15
