What is converse law of triangle of forces?
The converse triangle law is as follows. “If three forces or vectors acting at a point are in equilibrium then they can be represented both in magnitude and direction by three sides of a triangle taken in order.”
What is a triangle of forces in physics?
Definition of triangle of forces : a vector diagram whose sides represent three forces in equilibrium — compare force polygon.
What is converse of the law of polygon of forces?
Arun. 3 years ago. Converse of triangle law of forces-“If there forces or vectors acting a point are in equilibrium than they can be represented both magnitude and direction by three sides of any triangle taken in order”.
Is the converse of polygon law of forces true?
THe converse of the polygon of forces in not true. A number of polygons can be found whose sides represent the forces, all the polygons are similar; but any polygon with its sides parallel to the forces will not represent them.
What is equilibrium force?
If the size and direction of the forces acting on an object are exactly balanced, then there is no net force acting on the object and the object is said to be in equilibrium. Because the net force is equal to zero, the forces in Example 1 are acting in equilibrium.
What is the momentum triangle?
The equation for momentum is: p = mv. In a triangle equation, you cover the variable that you want to solve, and the other two line up like they are in the correct equation. This equation is sometimes called a ‘triangle equation. ‘ Put your mouse on the triangle for more information.
Is the converse of Polygon law of forces true?
What is the formula of triangle law of vector addition?
Triangle law of vector addition is used to find the sum of two vectors when the head of the first vector is joined to the tail of the second vector. Magnitude of the resultant sum vector R: R = √(P2 + 2PQ cos θ + Q2) Direction of the resultant vector R: ϕ = tan-1[(Q sin θ)/(P + Q cos θ)]
What are the conditions of equilibrium of coplanar forces?
The Coplanar Forces in Equilibrium The sum of forces must be zero. The sum of the moments of the forces about a point in the anticlockwise direction is equal to the sum of the moments of the forces about the same point in the clockwise direction.
What is the triangle law of force?
TRIANGLE LAW OF FORCE. According to this law if there are three forces acting over a body which is in equilibrium. then, the two forces are represented as a two side of a triangle in same order with scaling their magnitude to a suitable scale then the third side or the closing side of the triangle would be the resultant in opposite order.
What is the law of parallelogram and triangle?
Parallelogram and Triangle law of forces. If two forces acting at a point are represented in magnitude and direction by the two adjacent sides of a parallelogram, then their resultant isrepresented in magnitude and direction by the diagonal passing through the point. Parallelogram law of forces.
How do you find the resultant forces of a triangle?
If two forces acting at a point are represented in magnitude and direction by the two adjacent sides of a triangle taken in order, then the closing side of the triangle taken in the reversed order represents the resultant of the forces in magnitude and direction.
How do you know if three forces are in equilibrium?
If three forces acting at a point are in equilibrium, they can be represented in magnitude and direction by the three sides of a triangle taken in order. Note. The expression “ taken in order” means that the arrows representing the force directions must follow one another in the same direction round the triangle.
