Correction to Homework#2:

In the first part of the test, the angular momentum storage capacity is ± 523.6 N-m-s, NOT ± 5236 N-m-s.

Answers to emails received

There is no preferred method to solve the problems. You are completely free to use the tools you master better.

We cannot give any indication on how to solve the problems, or to let you know if you are doing things right. 

The initial conditions in the second part of the test are the same as in part 1. 


Second homework: Download the text (pdf) here.  

Email a working computer code (Matlab, Python, Fortran 77 or 90 or 96, C or C++) and a short note (in pdf!) with the mathematical procedure, results, comments and figures by Tuesday May 30 23:59:59 UTC to luciano.iess@uniroma1.it AND mircojunior.mariani@uniroma1.it . In the note indicate your FIRST NAME, LAST NAME, AND STUDENT ID (aka “numero di matricola”). Be concise and go straight to the point.


Challenge 2016-2017: Results
