Mechanical Engineering at the Nano Level a
Quantum Mechanical Approach

• Among the many potential applications of
  nano-technology, nano-machines are among the most
  exciting concepts.

What will be the necessary knowledge base of the
nano - engineer to design a nano-machine?
To what extent do the rules and laws of
engineering apply to the design and engineering
of nano devices and machines?
Can one translate the basic concepts which govern
bulk properties directly to the molecular, nano -
scale world?

We are engaged in a Quantum mechanical study of
basic mechanical engineering properties e.g.
?Elasticity, ?Youngs Modulus
Molecular Models
Specifically we address questions such as

• Does Youngs Modulus remain constant as the
  number of units increases?
• How does the combination of units in the same
  rod affect the mechanical properties?
• How does buckling affect the force constant in
  squeezing?
• How does a combination of two rods affect the
  overall performance? Is the additivity
• prevailing in the macro world retained?
• Can one relate the mechanical properties at the
  nano level to known chemical
• properties of the constituting elements
  (bond strength etc.)?
