Mechanical stability of tenuous objects
2014 Low-density structures such as colloidal aggregates become increasingly easy to deform mechanically as their size increases. We use recently-proposed scaling properties of such aggregates to investigate the effects of thermal fluctuations and of gravitational forces on such structures. For typical colloidal aggregates, made of 100 A particles, the diameter may not exceed 103 to 104 particl...
متن کاملInteractive Modeling of Mechanical Objects
Objects with various types of mechanical joints are among the most commonly built. Joints implement a vocabulary of simple constrained motions (kinematic pairs) that can be used to build more complex behaviors. Defining physically correct joint geometry is crucial both for realistic appearance of models during motion, as these are typically the only parts of geometry that stay in contact, and f...
متن کاملMulti fluidity and Solitary wave stability in cold quark matter: core of dense astrophysical objects
Considering the magneto-hydrodynamic equations in a non-relativistic multi uid framework, we study the behavior of small amplitude perturbations in cold quark matter. Magneto-hydrodynamic equations, along with a suitable equation of state for the cold quark matter, are expanded using the reductive perturbation method. It is shown that in small amplitude approximation, such a medium should be co...
متن کاملMechanical stability of proteins.
A number of experiments and experimentally based simulations showed that beta-proteins are mechanically more stable than alpha-proteins. However, the theory that might explain this evidence is still lacking. In this paper we have developed a simple elastic theory, which allows to estimate critical forces for stretching both kinds of proteins. It has been shown that unfolding of beta-proteins do...
