How is the angle between the vectors related to the resultant?

you use the inverse tangent function (or inverse sine or cosine). The resultant vector is (20, 20). The inverse tangent button on your calculator will always give you an angle between 90 degrees and –90 degrees. If your angle is not in this range, then you have to add or subtract 180 degrees.

What happens to the angle of the resultant as the angle between the two known vectors increases?

As θ increase, cosθ decreases. So, magnitude of resultant force decreases.

What is the effect on the magnitude of the resultant of two vectors when the angle θ between them is increased from 0 0 to 180 0?

When θ is increased from 0 to π, cosθ goes on decreasing. Therefore, the magnitude of the resultant will also go on decreasing.

What is the effect on magnitude of resultant of two vectors when the angle between them is increase from 0 degree to 180 degree?

If θ increases from 0∘ to 180∘ , the magnitude of cos θ decreases. As a result, the magnitude of R also decreases.

What is the angle between and if the magnitude of resultant and are equal?

Both the vectors have the same magnitude. Let the resultant have magnitude equal to vector A. Hence, the angle between the two vectors is 120°.

How does the angle between two forces affect the magnitude of the resultant?

The more extreme the angle, the smaller the resultant, up to a maximum loss at 180 degrees (when the forces directly oppose each other).

What should be the angle between the two vectors of same magnitude so that their resultant is equal to either of them?

How do you find the line of action of concurrent forces?

The line of action of each forces in coplanar concurrent force system are on the same plane. All of these forces meet at a common point, thus concurrent. In x-y plane, the resultant can be found by the following formulas:

What is the resultant of spatial concurrent force system?

Resultant of Spatial Concurrent Force System. Spatial concurrent forces (forces in 3-dimensional space) meet at a common point but do not lie in a single plane. The resultant can be found as follows: R x = Σ F x. R y = Σ F y.

What is the resultant of the coplanar concurrent force system?

Resultant of Coplanar Concurrent Force System The line of action of each forces in coplanar concurrent force system are on the same plane. All of these forces meet at a common point, thus concurrent. In x-y plane, the resultant can be found by the following formulas:

What is the resultant of three concurrent force polygons?

Resultant of three concurrent forces and more Basically it is a repetition of finding resultant of two forces The sequence of the addition process is arbitrary The “force polygons” may be different
