Parent Category: Mechanics
Statics is the branch of mechanics that describes bodies which are acted upon by balanced forces and torques so that they remain at rest or in uniform motion. In statics, the bodies being studied are in equilibrium.
Static Electricity The discharge of electricity between your finger and the doorknob is in principle the same as the discharge from a cloud to a tree during a storm. It occurs because of the general diffusive principle in nature (entropy) -- that is, things try to balance out to equal distribution. …

A concurrent force is a force that acts through the same point. When it is in equilibrium all the forces are balanced so there is no net or overall force. In fact, Newton's first law leads to the definition of inertia & equilibrium. when state of object does not change with time , we say the bod…
