What are the conditions of equilibrium when a number of parallel forces are acting on a body can a moving body be in equilibrium explain?

The first condition of equilibrium can be applied on concurrent forces that are equal in magnitude, since these produce translational equilibrium.
But if the forces are equal in magnitude but are non concurrent then even first condition of equilibrium is satisfied but torque is produced which does not maintain rotational equilibrium. Hence for complete equilibrium that is, both translational and rotational , both the conditions should be satisfied.

At what angle is the resultant force acting?
it is acting opposite the the equilibrium.
If an object has no net force acting on it?
it is in equilibrium.
What is the net force or the resultant force acting on an object in equilibrium?
0. An object in equilibrium has constant velocity, which makes its acceleration 0. Since net force=mass times acceleration, this would make the net force zero. Note that there could be multiple forces acting on the object, but since it is in equilibrium they would have to be equal and opposite in direction, to cancel all of the forces out. This would make the net force zero.
A ball thrown straight up has zero velocity at its highest point Is the ball in equilibrium at this point?
Yes, a ball is in equilibrium at the top of it's throw because there is a moment of no change, or equilibrium, when it is suspended in air.
Is there a net force acting on the freezer If so describe which forces interact and how they interact to produce the net force?
A net force is the result of all the forces acting on an object. If the freezer is at rest, it has no net force. The forces that would be acting on it would be gravity, and the normal (or perpendicular) force of the ground it's on (both would be the same as long as it's in equilibrium). You could also involve static friction as a force, which keeps it from moving sideways, if there were any parallel force acting on it (a force of gravity measured on the same angle of the plane it's on). So, if your freezer is on a slanted surface, those two forces would also be applicable. In conclusion, if your freezer is moving, there is a net force greater than 0. If the net force is zero, it is in equilibrium. I hope you got this in time, - Fellow physics student
Explain when a matter is in a state of equilibrium?
It is in equilibrium when the two conditions are satisfied - there is no net translational equilibrium and no net rotational equilibrium. For translational equilibrium, the summation of forces acting on the matter must equate to zero, which means that there is no resultant force. For rotational equilibrium, the sum of moments must be zero, which means there is no resultant torque. When these two conditions are met, the object will be stationary, i.e. it is in a state of equilibrium.
Explain the two conditions of equilibrium?
first condition for equilibrium is that the a body is satisfy with first condition if the resultant of all the forces acting on it is zero let n numbers of the forces F1, F2,F3,.........., Fn are acting on a body such that sigmaF=0 a book lying on a table or picture hanging on the wall are at rest and thus satisfy with first condition of equilibrium a paratrooper coming with terminal velocity also satisfies first condition of equilibrium
At what angle is the resultant force acting?
it is acting opposite the the equilibrium.
What quantities sum to zero when a system is in equilibrium?
For equilibrium, two conditions have to be met:* The sum (vector sum) of all forces acting on the object has to be zero (otherwise, it will start to accelerate). * The sum of all torques acting on the object has to be zero (otherwise, it will start to rotate).
Can a body in equilibrium if it is in motion?
It can be in equilibrium if in constant motion (constant velocity) as no forces are acting on it (no acceleration)
When is an object in equilibrium?
When the forces acting on the object are stable
How a body is said to be in equilibrium?
A body is mechanical equilibrium if the sum of the net forces acting upon it is zero.
What is difference between like and unlike parallel forces?
Forces which are parallel and acting in same direction are called like parallel forces. Forces which are parallel and acting in opposite direction are called unlike parallel forces.
What is the net torque acting on an object in rotational equilibrium?
There is none
Explain the Principle of Equilibrium and Free Body Diagram?
System is in the equilibrium if all the forces (external and reactional - internal) are in the equilibrium - resulting force is zero vector. Free body diagram is drawn for each body of the mechanical system. The body is disconnected from the system and contacts (sometimes called joints) are replaced by reactional forces. Then for each body equations of equilibrium can be written based on the principle of equilibrium.
What is a state in which all forces acting on an object are in balance?
Equilibrium is a state in which all forces acting on an object are in balance.
Why a body cannot be in equilibrium due to single acting on it?
A body is in equilibrium when the force on it is zero, thus if a single force is on the body, the force must be zero or the body will not be equilibrium.
