foundations of solid mechanics

. The digestive system consists of mouth cavity, pharynx, oesophagus, stomach, small intestine and large intestine. Mouth cavity consists of tongue and two rows of teeth. Saliva secreted by three large salivary glands and other smaller glands gets mixed with the food by the action of the tongue and..

Viscosity - When two solid surfaces slide over each other, a frictional force acts between them that opposes the relative motion of the bodies. Similarly, when a layer of a liquid slips on another layer the two exert a tangential force on another. This opposes their motion. The property o..

Introduction - A spider web is stronger than steel of the same thickness. Its elastic limit is greater than that of stee..

A mechanical wave is a periodic disturbance, which requires a material medium (solid, liquid or gas) for its propagation. These waves are also known as elastic waves because their propagation depends upon the elastic properties of the medium through which they pass. Exampl..

>Though shown in two dimensions this systematic long-range order is also found in three dimensions, with each Na + surrounded by six ions and vice versa. This order is due to strong coulombic forces of attraction between Na + and Cl - ions. Similar regular arrangements are found in other solid..
