Yakov M Tseytlin is a mechanical engineer, educator, and research scientist with MS in Mech. Eng., PhD, Doctor of Tech. Sci., worked 25 years at Mendeleev Metrology institute, Russian academic institutions; project Eng. and senior researcher in American companies since 1992; now independent researcher. Main field of study: precision elasticity.

This book presents results of the author's and many other researchers work in the development of the micro-nanomechanics structural methods and effective applications. It shows close relations between micro-nanomechanics and tiny biomechanics of molecular cells including elasticity of DNA. Micro-nanomechanics in recent decades has attracted the attention of many researchers, engineers, and students in the field of instrumentation, measurement, physics, astrophysics, and biophysics. Precision elasticity solutions in this book presented on the basis of reliable approximation methods with accurate enough results in comparison with experimental and computerized FEA methods. The author developed methods of uncertainty negligibility and structural stability evaluation, precision measurements of tiny objects by atomic force microscopy with increased accuracy, traceability of thin coatings thickness measurements, effective tractable methods of calculation for compliance of concave flexure hinges, precision helicoidal sensors, and new quasi-universal models of DNA elasticity.
