Best Answer

" If a number of forces acting at a point be represented in magnitude ad direction by the sides of a polygon in order, then the resultant of all these forces may be represented in magnitude and direction by the closing side of the polygon taken in opposite order "

Yes


Define triangle law of forces and polygon law of forces?

Three forces in equilibrium can be represented in magnitude and direction by the three sides of a triangle taken in order. If a number of forces acting simultaneously on a particle be represented in magnitude and direction by the sides of a polygon taken in order, their resultant may be represented in magnitude and direction by the closing side of the polygon taken in opposite order.


What is the Definition of polygon law?

All the concurrent forces acting at a point can be represented by a polygon's sides closing with the resultant force equal in magnitude and opposite in direction.


Statement of polygon law of forces?

if several COPLANAR FORCES are acting at a point simultaneously such that each one of them can be represented in direction and magnitude by a side of a polygon, taken in order, then the resultant is given by the closing side in the reverse order

Explain why the polygon of forces must close when a body is in equilibrium?

The polygon of forces must close in equilibrium to satisfy the condition that the net force acting on the body is zero. If the forces do not close, it would indicate there is a resultant force acting on the body, causing it to accelerate rather than being in equilibrium.


Why is the polygon method reasonable graphical technique?

The polygon method is most suitable graphical technique for analyzing concurrent forces because it allows for the graphical addition of multiple vectors without the need any complex calculations. This method is particularly useful when dealing with systems of forces acting at a single point or in a plane. By using the polygon method, can visually determine the resultant of multiple forces, which simplifies the analysis and helps in understanding the overall effect of the forces on a system


How the polygon of force obtained by experiment?

The polygon of forces can be obtained experimentally by applying multiple forces to an object and measuring their magnitudes and directions. By drawing vector representations of these forces to scale and closing the shape of the polygon, the resultant force can be determined. This method helps visualize the equilibrium or resultant force acting on the object.


If the force polygon is not a closed figure what does it indicates?

That the forces sum to a non-zero resultant.


Which law of motion describes equal and opposite forces of action and reaction?

Equal and opposite forces was Newton's recognition of equal anti-parallel forces, or the sum of the forces is zero in Equilibrium.


What is polygon law of vector addition?

THE POLYGON LAW states that if (n-1) similar vectors acting at a point in a plane can be represented both in magnitude and direction by the (n-1) consecutive sides of a n-sided polygon then the n-th side will represent the resultant vector in the reverse order.


What is the relationship between balanced force and first law of motion?

The first law is the sum of the forces is zero or the forces are balanced.
