SUMMARY
The equation for calculating the resultant force in Engineering Statics is given by F^2 (resultant) = F1^2 + F2^2 - 2F1F2cos(theta). The magnitude of the resultant force can be simplified to F (resultant) = F sqrt(2 - 2cos(theta)). To solve for the angle between two forces, one can use the dot product formula, \vec a·\vec b = |a||b|cos(φ), and apply symmetry when the magnitudes of the forces are equal, leading to the conclusion that the angle is θ/2.
