Answer:

The diagonal of the parallelogram PBCA is the resultant force R, which forms two scalene triangles with the forces F1 and F2. Since the sum of all the angles within a triangle is 180°, we can write γ function of α and β. The resultant force can also be calculated analytical, using force projections.

Answer:

In order to calculate the magnitude and direction of a resultant force or to calculate the value of one force component or another, we can use the law of sines and the law of cosines.

...

The forces and angles are as follows:

F1 = 2.91 N, α1 = 0°

F2 = 2.67 N, α2 = 60°

F3 = 2.47 N, α3 = 150°

F4 = 2.23 N, α4 = 270°
