How can you calculate parallel force?
Parallel forces are forces acting in parallel lines. If two parallel forces act in same direction, they are called like parallel forces. If two parallel forces act in opposite directions, they are called unlike parallel forces.
What are the conditions for the complete equilibrium of a body?
when vector sum of all forces and all torques is zero.
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.
What are the conditions necessary for equilibrium in so far as linear motion is concerned Cite examples of moving bodies in equilibrium?
First condition for equilibrium. Insofar as linear motion is concerned, a body is in equilibrium if there is no resultant force acting upon it, that is if the vector sum of all the forces is zero. This condition is satisfied if the vector polygon representing all the external forces acting on the body is a closed figure.Equilibrant of a Set of Forces: This is defined as that single force that must be applied to keep a body in equilibrium when it is under the action of other forces. This equilibrant (sometimes called anti-resultant) must be equal in magnitude and opposite in direction to the resultant of the applied forces.http://blog.cencophysics.com/2009/08/composition-resolution-concurrent-forces-vector-methods/
How to make a system of forces in equilibrium just by changing the angles of forces?
By the changing the angles of forces, the system of the forces will be in equilibrium.
What is the necessary condition for equilibrium of system of coplanar forces?
Coplanar or not, the two conditions for equilibrium are:The sum of all forces must be zeroThe sum of all torques must be zero.
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.

Can an object be moving and still be in equilibrium?
No. For a body to be in equilibrium it must be acted on by either no forces, or by several forces such that their vector sum (the net force) is zero. -- This was my original post, Silverbullet89, I just forgot to sign in first... But dont you think that when we sit, then a single fore weight acts on it???

What is meant by like and unlike parallel forces?
Like Parallel forces are the forces that are parallel to each other and have same direction. Unlike parallel forces are the forces that are parallel but have directions opposite to each other.
What are the two forces that are in equilibrium in a star?
Hydrostatic and Equilibrium
What is the 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.
