how do u find the angle of a resultant force?

Answer 1

Brake the force down into it's corresponding horizontal and vertical parts. Then get the tangent of the angle.

Answer 2

A net force (also known as a resultant force) is a vector produced when two or more forces act upon a single object. It is calculated by adding the force vectors acting upon the object.

* When force A and force B act on an object in the same direction (parallel vectors), the net force (C) is equal to A + B, in the direction that both A and B point.

* When force A and force B act on an object in opposite directions (180 degrees between then - anti-parallel vectors), the net force (C) is equal to |A - B|, in the direction of whichever one has greater absolute value ("greater magnitude").

* When the angle between them (the forces) is anything else, then the individual components must be added up using sine and cosine.

(Note: the illustration assumes that the object, in this case a square, has no center of mass and can be treated like a point.)

Answer 3

1. Draw the parallelogram of forces.
2. Use it to first find the resultant by the cosine rule.
3. Then find the angle you seek by the sine rule.

Answer 4

Using the parallelogram law or triangle law resolve the vector(break the force into its components)the diagonal is the resultant force & then use the formula to find the angle.

Answer 5

After you've broken your two vectors into their x and y components via

Vx = V cos(angle)
Vy = V sin(angle)

you can then add like components. To find the new resultant angle you need to take the inverse tangent of Vy / Vx, and it's magnitude is the square root of the sum of Vx squared and Vy squared.

Answer 6

tan-1=y/x
in other words : in a calculators is the inverse tan of the y value divide by the x value of the resultant force.
