I hung a board attatched to a piece of string and twisted it to calculate 
moment of inertia. Does this torsional pendulum work like a mobile? Also, 
about the torsional constant, does it double if the string length of the 
pendulum is cut in half? A spring constant will double if the spring is 
cut in half so does it work the same way for the torsional pendulum?
