The pressure exerted by a liquid on the base of the container depends on the vertical height of the liquid over it not on the area of cross-section. As one goes deeper in the swimming pool, the pressure on the ear drum is found to increas..

Principle of Flotation - When a body floats in a fluid, it displaces an amount of fluid equal to its own weight. The apparent weight of a floating body is zero. Hydrometers and submarines use the principle of flotation. Words to Remember:- Fluid, Atmosph..

Any liquid or gas produces upthrust. For example, the upthrust of air keeps a hot air balloon u..

The thickness of the metallic rope needed to lift a given load is decided using the knowledge of elastic limit of the material of the rope and the factor of safety. Electric poles are made hollow A hollow shaft is found to be stronger than a solid one because the torque required to twist a hollow c..
