The answer is in the definition: polygon of forces(plural polygons of forces) # (mechanics) A polygonal figure the sides of which are vectors representing several forces acting simultaneously upon one point, so that the vector necessary to make the figure closed is the resultant of those forces.

Why are chemical reactions that have equilibrium points close to completion preferable for manufacturing?
ans 1=when the rate of reverse reation become equals to rate of forward reaction,such chemical reation is in equilibrium
When is reaction in chemical equilibruim?
a reaction is in chemical equilibrium when the rate of evaporation is equal to the rate of condensation. molecules are leaving and returning to the container at the same rate. Equilibrium can only be reached in a close container.
What is cell specialisation?
The quasi-balanced state of a thermodynamic system near to thermodynamic equilibrium, in some sense. In a quasistatic or equilibrium process, a sufficiently slow transition of a thermodynamic system from one equilibrium state to another occurs such that at every moment in time the state of the system is close to an equilibrium state. During a quasistatic process, the system reaches equilibrium much faster, almost instantaneously, than its physical parameters vary.
When a chemical reaction and it and reverse are occurring at the same time and at the same rate the reaction has achieved?
equilibrium
Forces can hold groups of atoms together in?
The forces that hold groups of atoms together are the strong nuclear forces. It has a short range, which means that particles must be extremely close before its effects are felt.
What is an open polygon?
No it CANT be a polygon because its open a polygon has to be close
What is a good sentence with the word polygon in it?
The polygon is a close figure.
What is the difference between an ogive and a frequency polygon?
The ogive never close because they represent non-decreasing functions, and polygon you close it.
What is a close plane figure with 3 or more sides?
It is a 'many sided' polygon
Can a polyogon have 19 sides?
yes it can, in fact a polygon can have any amount of sides.. just some don't have names. a polygon is a polygon as long as the lines close at an edge, its a polygon.
What is the answer of a close figure formed by straight line segments?
A polygon.
What is a close plane figure founded by segments which are the sides?
polygon
Why must a polygon have 3 or more sides and angles?
A polygon must be a closed region without any curves or arches. so you cant close one or two segments to form a polygon
A close figure made up of 3 or more line segments?
polygon
What polygon that have 1 million sides?
A shape very close to a circle or an oval.
What is a close geometric figure made up of three or more line fragments?
A polygon.
What is a close figure made up of line segments called?
It is called a Polygon.A polygon
