Solve problem 2.2 by applying two pairs of forces with moments of equal magnitude and opposite sign to the system. 2.2. Two parallel and identically directed forces F1 and F2 are applied to a solid surface. Prove that: a) the modulus of the resultant force is equal to the sum of the moduli of the summand forces; b) the resultant is parallel to the summed forces and directed in the same direction; c) the resultant passes through the center of parallel forces, i.e. through a point that divides the distance between the points of application of the added forces into segments. inversely proportional to the moduli of these forces.
