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 does the law of cosines reduce to when dealing with a right triangle?
D. The Pythagorean Theorem
Why Lami's theorem cannot be used for 4 concurrent forces?
Because, this theorem comes from the law of sines which is completely a triangle law and the law of sines can not be applied on other polygons.
What type of triangle has angle A 37 degree angle B 56 degree angle C 87 degree?
Acute triangle - all of the angles are less than a right angle (90°).Scalene triangle - none of the sides or angles are congruent. It can be shown that if no two angles are the same, then no two sides are the same using the Law of Sines and Law of Cosines.
What is the formula for finding current?
See OHMS LAW on the internet with a search engine. It will explain everything.
How do you make vector representation?
explain the vector representation of Coulom's law.
What is the triangle law of vectors?
If three vectors form a triangle , their vector sum is zero.
Can the triangle law of vector addition be used for many vectors?
no because triangle only contain three vectors and if many vector are added then they cant form a triangle
What is the vector triangle?
The "vector triangle" illustrates the "dot product" of two vectors, represented as sides of a triangle and the enclosed angle. This can be calculated using the law of cosines. (see link)
Does law of vectors means triangle law of vector?
ya they just accidentally said law of vectors instead.
What is triangle law in vectors?
A law which states that if a body is acted upon by two vectors represented by two sides of a triangle taken in order, the resultant vector is represented by the third side of the triangle.
What does vector mean in science terms?
Any physical quantity which has both direction and magnitude is called a vector. A quantity must also obey the 'Triangle law of vector addition' to be called as a vector. For example displacement is a vector, u can say a person moved 5 km (magnitude) along west(direction). But electric current is not a vector, it has magnitude and its direction is from +ve terminal to -ve terminal but it doesn't obey triangle law. Rather currents are added as scalars.
What is the difference between parallelogram law of vector addition n triangle law of vector addition?
There is basically no difference. They are nothing more than 2 different visualizations of how we can graphically add two vectors.strictly if we say there is one and only difference is that---Triangle law of vector addition states that when 2 vectors r acting as the adjacent sides of a triangle taken in order. third side of the triangle will give the magnitude of th resultant 7 direction is in opposite order.Parallelogram law of vector addition states that if 2 vectors r acting as the adjacent sides of a parallelogram, then the diagonal of parallelogram from the point of intersection of two vectors represent their resultant magnitude & direction.
How do you verify triangle law of vector addition?
If the three sides of a triangle are represented by vectors then the sum of two sides in same direction is equal to the third side in opposite direction..
Why the direction of resultant vector in the triangle law of addition is reverse?
In order to bring the system to equilibrium, action and reaction cancel out. The resultant is the reaction.
Is it necessary that every vector has to obey the law of vector addition?
Yes.
