Hydrostatic and Equilibrium
Dynamic equilibrium.
The balance of forces that keep a star from collapsing is called hydrostatic equilibrium. This equilibrium is maintained between the inward force of gravity and the outward force generated by gas pressure within the star.
In a star, the force of gravity is trying to collapse the star inward, while the pressure from nuclear fusion in the core creates an outward force, resisting the gravitational collapse. These two forces are balanced in a stable star, leading to a state of equilibrium.
The two types of equilibrium are static equilibrium and dynamic equilibrium. Static equilibrium is when an object is at rest, while dynamic equilibrium is when an object is moving at a constant velocity with no acceleration. Static equilibrium involves balanced forces in all directions, while dynamic equilibrium involves balanced forces with movement.
If three concurrent forces are in equilibrium, then each force is proportional to the resultant of the other two forces. This means that the magnitude and direction of each force are determined by the other two forces, ensuring that the system remains in equilibrium.
Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance.
You say that the two forces are in equilibrium.
Inside a star, there are two opposing forces at play: gravity tries to pull the stellar material inward, compressing it, while the force of nuclear fusion in the star's core pushes outward, generating energy and counteracting gravity to maintain the star's stability. These forces must balance each other for the star to remain in a state of equilibrium.
When two forces are equal in magnitude and opposite in direction, we say they are balanced or in equilibrium.
Equilibrium.
The forces are said to be in equilibrium in that case.
Yes, an object can still be in equilibrium even if it's acted on by two forces that are not perpendicular. The forces just need to have equal magnitudes and be in opposite directions along the same line of action. This condition ensures that the net force on the object is zero, leading to equilibrium.
