lved in its rectangular components
A force can be resolved into rectangular components by identifying its horizontal and vertical components. This can be done using trigonometry, specifically sine and cosine functions. The horizontal component is found by multiplying the magnitude of the force by the cosine of the angle it makes with the horizontal axis, and the vertical component is found by multiplying the magnitude of the force by the sine of the angle.

1) Graphically. Draw an arrow for the force, and measure the vertical and horizontal components. 2) Use trigonometry. The x-component is the length of the vector times the cosine of the angle, while the y-component is the length of the vector times the sine of the angle. 3) Use the polar-to-rectangular conversion on your scientific calculator. This is the fastest method, but the details are a bit complicated (since the calculator needs to return two values), and vary from one calculator to another. Check your calculator's manual.
Force can be resolved into horizontal and vertical components using vector analysis. However stress cannot be resolved into horizontal and vertical components using vector analysis since it is not a vector but a tensor of second order.
For simplicity consider a force whose direction does not correspond to either the x- or y-axis. At the head of the force (where the arrow is) draw a vertical line to the horizontal axis and a horizontal line to the vertical axis. The force is now enclosed by the lines you have drawn and the axes and this enclosure is a rectangle. Since a rectangle is also a parallelogram this means that you have also resolved the given vector into two components, namely, the one given by the portion of the horizontal axis between the origin and where your vertical line meets that axis, and the one given by the portion of the vertical axis between the origin and where your horizontal line meets that axis. These two vectors are the rectangular components of the given force.

A vector can be resolved into infinitely many sets of components in both 2D and 3D space.
A vector can be expressed in terms of its rectangular components by breaking it down into its horizontal and vertical components. These components represent the projection of the vector onto the x and y axes. The vector can then be expressed as the sum of these components using the appropriate unit vectors (i and j for x and y directions, respectively).
No, a vector in 3-d space would normally be resolved into 3 components. It all depends on the dimensionality of the space that you are working within.
The angle between the rectangular components of a vector can be calculated using trigonometry. You can use the arctangent function to find the angle. For example, if you have a vector with components (x, y), the angle would be arctan(y/x).
Nonperpendicular vectors need to be resolved into components because the Pythagorean theorem and the tangent function can be applied only to right triangles.
Not necessarily.
