This is an *online calculator resultant force* with the capability to calculate the resultant force of several forces, up to 4 in total in a concurrent force system. The forces and angles must each be entered as positive numbers, the calculated resulting force and its angle are output graphically and as a numerical value. The resultant force F_{R} is shown in orange.

### An example

Did something go wrong? Here is an example of what it should look like:

The force F_{1} is 5 N, with an angle of 45 °. The second force F_{2} is 7 N, but the angle here is 215 °, the third 5 N and 7 ° and the last force 6 N and 165 °. The result appears the moment you have entered the last number and should now look like this:

The *online calculator resultant force* shows a resultant force with the first force entered, which is then identical to the force entered. If not all forces are entered, the calculation is carried out anyway. In this way, the resulting force for 3 forces or the resulting force for 2 forces can be calculated.

Here you can find exercises about resultant forces.
