Problem: A rope tied to the top of a flagpole pulls with 400 N at \(60^\circ\) below the horizontal. Seen from above, the rope points \(30^\circ\) east of north. With \(x\) east, \(y\) north and \(z\) up, find the components of the rope force.

Describe a force in 3D with i, j, k components, its magnitude, coordinate direction angles and unit vector.
Write a force by its x and y components, in scalar and Cartesian vector form, and get its magnitude and direction back.
Write a cable or rope force as a Cartesian vector from the coordinates of two points, using position and unit vectors.
Add concurrent forces in space component by component and find the magnitude and direction angles of the resultant.
Build a force in space from its components, its three direction angles, two angles or two points, turn the 3D view with the mouse, and add several forces into one.
See what the dot product means: the angle between two directions and the part of a force along a line, drawn in 3D with its perpendicular part and a right-angle mark.
Add any number of forces in a plane with a clear component table and a force polygon, or find the force that is missing, that balances the others or that turns the resultant to a wanted direction.
Split a force into two parts along any two directions, perpendicular or not, or into x and y parts from an angle or a slope, with every step shown on the drawing.
