This following applet is Blocks and center of gravity
Created by prof Hwang Modified by Ahmed
Original projectBlocks and center of gravity
This is a home work problem shown in many Fundamental Physics textbooks .

  * How to stack four uniform blocks on top of a table, so that they extend as far right as possible and still remain stable.
  * How should each be positioned?
  * Can the top block have its entire length beyond the edge of the table.

You need to change "msg" to "%msg%" to tell EJS use variable name "msg" instead of string value "msg".
It might be due to EJS version. This one was created very long time ago!
