Description and Types of the Equilibrium State

1246 Words5 Pages
Objects in equilibrium state are defined as isolated objects with precise constant properties such as pressure, temperature and volume. In addition to that the total net force a nd acceleration must be equal to zero (1). Achieving equilibrium state requires knowledge in all object’s properties and behavior. The following research paper will carry the outcomes of our research in the topic, starting with a simple description of the types of the equilibrium state, followed by engineering and mathematical explanations to the topic. After that it will show examples from mechanical engineering classwork and world applications of the topic. The paper will close with the problems faced while completing the research. Description and types of equilibrium state Equilibrium is a state of balance in which the addition of all forces applied on a system is equal to zero. There are three states of equilibrium: unstable, stable and neutral. Stable equilibrium is when any sort of movement will raise the object’s potential energy, an object that moves with a stable equilibrium tend to go back to its initial place. Unstable equilibrium is when any motion will lower the object’s potential energy and the object will not be able to fall back to it’s original position easily without using additional energy. Furthermore, an object experience neutral equilibrium when any type of motion has no effect on the potential energy of the object itself therefore the equilibrium will remain the same. (2) Engineering description of the equilibrium state An engineering description differs from the layperson description because the engineering description defines the subject in a scientific way were the people can understand the subject deeply.
