Access Revision Notes for Class 11 Physics Chapter 9 Mechanical Properties of Fluids 1. Fluid Mechanics: The term ‘fluids’ are generally used to express both liquids and gases. In other words, it can be said that the substances which have the potential to flow are termed as fluids. Fl...
Ans:Viscosity could be defined as the property of a fluid by virtue of which an internal frictional force comes into play when the fluid is in motion and would oppose the relative motion of its different layers. 11.What is the significance of Reynolds’s Number? Ans:We know that, Reynolds...
This is characterised by a gradient of stiffness responsible for the differentiation of the stem cells14. In this respect, control over the Young’s modulus of such materials is extremely limited. Herein, we show for the first time the creation, tuning and control of mechanical property in ...
The response of carbon nanotube ensembles to fluid flow: Applications to mechanical property measurement and diagnostics We demonstrate an experimental method to understand the mechanical response of carbon nanotube (CNT) ensembles to fluid flow through the measurement of the...

A process of reducing the dimension of the phase space of a mechanical system by identifying phase space points that are related by a symmetry. Equivariance: Equivariance of a momentum map is a property that reflects the consistency of the mapping with a group action on its domain and range....
The details of the homogenization method and homogenization analysis of 2D and 3D extremal metamaterials are summarized in Supplementary Notes 1, 2 and 5. Kinematic property of the 3D metamaterial unit and the experiments and reconfiguration on 3D metamaterial are described Supplementary Notes 3, 4 an...
Up until the Industrial Revolution, the dynamic mechanical properties of materials were only of importance in warfare, particularly after the powder-driven
In the recent past, several investigations are performed for the property enhancement of FSSW welded joints especially on the mechanical and metallurgical characterization. In this work, an attempt has been made to analyze the effect of environmental conditions on the output quality characteristics of ...
Using idempotency and the left null-space property (3.31) the working stress SA=PˆS becomes complementary to the workless stress (Definition 3.6), see Proposition 3.5.Example 3(Angle preservation/unshearability)For the angle preservation constraint (3.17) with \(a=1\) and \(b=2\) the ...
Needles, as some of the most widely used medical devices, have been effectively applied in human disease prevention, diagnosis, treatment, and rehabilitation. Thin 1D needle can easily penetrate cells/organs by generating highly localized stress with their sharp tips to achieve bioliquid sampling, bio...
