Sometimes you have to strip away all the non-essential parts to see an idea at work. Neil Downie proposes a clever study of the exchange of speed for force. A second array of pulleys float between input pulleys and the output pulley. An elegant display of force in motion.
Counting on friends: what can your little acrobats tell you about the changes in speed or
