introduction to static equilibrium physics

) who experimented with electricity and made major inroads in understanding the phenomenon. Alessandro Volta By the middle of the eighteenth century, there were machines that could generate large electrical charges. Static electricity may produce dramatic effects but it is of very little ..

Equilibrium of Rigid Bodies - A rigid body is said to be in equilibrium if, both the linear and angular momentum of a rigid body have a constant value. For the equilibrium of a rigid body, the body need not be at rest. However, if it is at rest, it is called the s..

Fluids - Fluids are substances which begin to flow when external force is applied on them. Liquids and gases are fluids. Fluids do not have a definite shape. The branch of physics, dealing with the study of fluids at rest is called hydrostatics. When fluids are kept in a container, due to..

Consider a sample of an ideal gas kept in an enclosure. The state of the gas is described by specifying its pressure P, volume V and temperature T. If these parameters can be uniquely specified at a time, we say that the gas is in thermodynamic equilibrium. If we put the enclosure on a ho..

Static friction is the friction experienced when we try to move a stationary body on a surface, without actually causing any relative motion between the body and the surface which it is on. It can be defined as the force of friction which exactly balances the applied force during the stat..

Static Electricity - Static electricity was known to people more than 2500 years ago. The Greeks knew about the attractive property of the resin amber. They knew that by rubbing amber with cloth, it could be made to attract small feathers. The Greek name for amber was 'elektron'..

The maximum force of static friction is independent of the area of contact. The maximum force of static friction is proportional to the normal force i.e., if the normal force increases, the maximum external force that the body can withstand without moving, also increases..

Summary - When substances like glass and silk or ebonite and fur are rubbed, positive and negative charges of equal amount are simultaneously produced. Like charges repel, unlike charges attract. Electroscope is the device used for detecting the charge on a body. The divergence of the leaves of the..
