What does it mean if something is in static equilibrium? :
equilibrium of a system whose parts are relatively at rest
(such as a steel truss resting on piers)
What does it mean if an object is in static equilibrium?
An object is in static equilibrium if and only if:
The sum of the forces on it in each direction is zero
. The sum of the torques on it in each direction is zero. Its linear momentum is zero (i.e. it’s not moving).
What is static equilibrium in simple terms?
What is static equilibrium in physics example?
What is the difference between static vs dynamic equilibrium?
What is the difference between static and non static equilibrium?
Definition. Dynamic equilibrium is an equilibrium where reactants are converted to products and products are converted to reactants at an equal and constant rate.
Static equilibrium is an equilibrium that occurs when all particles in the reaction are at rest, and there is no motion between reactants and products
.
What is static equilibrium quizlet?
Static equilibrium.
An analysis of the forces and torques on a system at rest or at a constant velocity
.
How can we say that a body is in static equilibrium?
A body is in equilibrium when it remains either in uniform motion (both translational and rotational) or at rest.
When a body in a selected inertial frame of reference neither rotates nor moves in translational motion
, we say the body is in static equilibrium in this frame of reference.
Why is static equilibrium important in physics?
Static equilibrium is an important concept in the design of countless rigid structures, from the floor system of a house to an enormous suspension bridge,
because these structures must maintain static equilibrium under all expected loading conditions
.
What is the difference between dynamic and static equilibrium with regards to homeostasis?
Terms in this set (15)
Dynamic equilibrium is homeostasis isn’t always the same but it is maintained within a range.
Static equilibrium is homeostasis doesn’t change. Stimulus is change in environment, and homeostasis regulates the change.
Which of the following is an example of static equilibrium quizlet?
Which of the following states the conditions of static equilibrium?
How many forces act on an object that is in static equilibrium?
Analyzing a Static Equilibrium Situation
The state of the object is analyzed in terms of the forces acting upon the object. The object is a point on a string upon which
three forces
were acting. See diagram at right. If the object is at equilibrium, then the net force acting upon the object should be 0 Newton.
What is the difference between static and dynamic equilibrium quizlet?
What is the difference between static equilibrium and dynamic equilibrium? They both have zero net force (equilibrium), but
static is when they’re at rest, and dynamic is when they’re moving (constant speed, straight line)
.
How do we come to know whether our reaction is at static equilibrium or dynamic equilibrium?
If you observe reactions at dynamic equilibrium and reactions at static equilibrium, neither will have visible changes occurring, and it’ll look like nothing is happening
. However, reactions at static equilibrium are actually very different from those at dynamic equilibrium.
What is meant by static and dynamic equilibrium as they relate to the ear and balance?
The ear maintains both static and dynamic equilibrium. Static equilibrium is maintenance of the proper head position in response to changes in linear motion such as walking. Dynamic equilibrium is the maintenance of proper head position in response to rotational movement such as turning.
Which of the following structures is involved in static equilibrium quizlet?
Where are static equilibrium receptors located?
Can a moving object be in static equilibrium?
What is the structure of the Maculae that is involved in static equilibrium quizlet?
Sensory receptors for static equilibrium are found in the MACULA,
a complex of structures found in the SACCULE and UTRICLE of the VESTIBULE in the inner ear
. There is a macula in both the saccule and utricle. Each responds to vertical and horizontal movements, respectively.
What are the two types of equilibrium quizlet?
Which of the following structures in the inner ear is essential for maintaining static equilibrium quizlet?
The vestibular system
is the sensory apparatus of the inner ear that helps the body maintain its postural equilibrium.
What is an example of static equilibrium in everyday life?
What are some examples of static rotational equilibrium?
Examples:
Level, bottle opener, dolly, wrench, screw driver
…. If the torque causes a counterclockwise angular acceleration, it is positive; if it causes a clockwise angular acceleration, it is negative. Static equilibrium occurs when an object is at rest – neither rotating nor translating.
What is an example of equilibrium?
An example of equilibrium is in economics
when supply and demand are equal
. An example of equilibrium is when you are calm and steady. An example of equilibrium is when hot air and cold air are entering the room at the same time so that the overall temperature of the room does not change at all.
What is an example of a dynamic equilibrium?
Dynamic Equilibrium Examples
The reaction, NaCl(s) ⇌ Na
+
(aq) + Cl
–
(aq), will be in dynamic equilibrium when the rate of the dissolution of the NaCl equals the rate of recrystallization. Another example of dynamic equilibrium is
NO
2
(g) + CO(g) ⇌ NO(g) + CO
2
(g)
(again, as long as the two rates are equal).
