- Your WebQ question for the day
will be the following -- ask questions in class to help you answer it!
- We have talked briefly about engineered self-assembly today. A
closely
related topic is self-reorganization. Consider a robotic arm that is
supposed to self-reorganize between two states. [This may remind you of
the Terminator!] In state A, the arm is very flexible with a Young's
modulus close to 2 GPa. In state B, the arm is stiff with a Young's
modulus larger than 160 GPa. Assume that this arm is made of a large
collection of small parts. Come up with a simple design for a system
that can perform the above operation (you can decide on the details of
the system). Now:
- a) present an energy argument and show how much energy is
needed to go from one state to another
- b) estimate how fast these transitions can take place
you may be interested to know that
there are people who work on building systems similar to what is
described above!
