Force Resolver: Split a Force Along Any Two Directions

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.

Coplanar Force Resultant: Table, Polygon and Missing Force

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.
