Can an object be in mechanical equilibrium when only a singel force acts on it?

If only a single nonzero force acts on an object, it will not be in mechanical equilibrium. There would have to be another or other forces to result in a zero net force for equilibrium.

Can an object be in equilibrium when only a single force acts on it?

No: equilibrium requires forces to be balanced, so it requires (at least) two forces, unless there are zero forces acting.

Does an object in mechanical equilibrium have no forces on it?

If an object is in mechanical equilibrium, the net force on it must be zero. All the forces acting on the object add to zero.

Can an object ever be in equilibrium if it is acted?

Yes! Such an equilibrium situation is called dynamic equilibrium . A body is said to be in equilibrium if the net force acting on the body is zero. ... Dynamic Equilibrium : When the net force acting on an object is zero and if the object is moving at a constant non-zero velocity, then it is called dynamic equilibrium.

When an object is in equilibrium the forces acting on the object are?

If an object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations. Thus, the net force is zero and the acceleration is 0 m/s/s. Objects at equilibrium must have an acceleration of 0 m/s/s.

Can a moving object be in mechanical equilibrium?

Objects in motion can also be in equilibrium. A child sliding down a slide at constant speed would be in mechanical equilibrium, but not in static equilibrium (in the reference frame of the earth or slide). Another example of mechanical equilibrium is a person pressing a spring to a defined point.

When forces acting on an object are in equilibrium the object can still be moving?

Because there is no net force acting on an object in equilibrium, then from Newton's first law of motion, an object at rest will stay at rest, and an object in motion will stay in motion. Let us start with the simplest example of two forces acting on an object.

Which of the following forces Cannot be in equilibrium?

8,4,13 8 , 4 , 13 cannot be in equilibrium.

Why can single force system be in equilibrium?

If there is only one external force (or torque) acting on an object, it cannot be in equilibrium. True, as the sum of forces cannot be zero in this case unless the force itself is zero. If an object is in equilibrium there must be an even number of forces acting on it.

Under what conditions will an object be in equilibrium?

An object is in equilibrium in a reference coordinate system when all external forces (including moments) acting on it are balanced. This means that the net result of all the external forces and moments acting on this object is zero.

Can only one force act on an object?

If only one force acts on an object, the object cannot have zero acceleration (Newton's second law). It is possible for the object to have zero velocity, but only for an instant. For example (if we neglect air resistance), a ball thrown up into the air has only the force of gravity acting on it.

When three forces acting at a point are in equilibrium then?

Explanation: Lami's theorem: It states that if three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two forces. Consider three forces FA, FB, FC acting on a particle or rigid body making angles α, β and γ with each other.

What happens when forces are not in equilibrium?

– If the net force on an object is not zero, it is not in equilibrium (that is, a change in velocity will occur), and thus Newton's Second Law must be used to determine its motion.

How does the triangle of forces show that the object is in equilibrium?

Figure 4: You can determine whether forces are in equilibrium by arranging them in a triangle. The mathematical method involves resolving the forces into horizontal and vertical components. If the sum of the components of the forces equals 0 then the object is in equilibrium.

When no forces act on moving objects their paths are normally?

straight lines. When no forces act on moving objects their paths are normally straight lines.

When a ball is tossed straight up is it in equilibrium?

1 Expert Answer

In particular, it is definitely not in equilibrium when it reaches the top of its path, where the velocity is momentarily zero. Here's why: The definition of equilibrium is that there is no net force acting on the object, as you state correctly.
