EQUILIBRIUM OF A FORCE SYSTEM IN SPACE
A structure of two welded plates is fixed at point A by a ball joint, at point B by a cylindrical hinge, and at point
C by supporting rod. Two forces, F1 = 10 kN applied at point K at angle α1 = 30o
and F4 = 14 kN applied at
point H at angle α4 = 60o
, and couple M = 4 km are acting on the structure. Dimension a = 0.6 m. Not taking
into account the deadweight of the plates, determine the reactions of the supports A, B and C. Verify the solution. Please, do with verification and explanation.
