I try to find forces in this task. The Mathcad 15 sheet is in attach. Are equations in the Given-Find block right?

What is the 8-th equation?

I have solved ODEs

see Hello, World! See my 1-st Prime Animation!

than I have deleted derivatives and got solution of same static task about 3 mass on the string

Thanks to all!

But no solution in Mathcad 15 - different units in vectors! Do you know solutions?

Thanks!

It will be a chapter for one new book with description of main tools of Mathcad.

Toby!

The more useful for PTC title of the article is

Physics and Mathcad: a funicular polygon in statics, kinematics and dynamics
or
Newton vs Lagrange

OK?

How is the process of translation?
