He geometry of the Microwave Bags flat statically determinate truss with two fixed hinge supports is specified by the lengths of the rods, the number of panels in supporting parts and the number of panels in the bolt.By induction on these parameters the General formulas for the deflection of the trusses under the action of concentrated and distributed load are obtained.Symbol conversions are performed in the system of computer mathematics Maple.The asymptotic properties of solutions are found.Formulas for reactions of supports and MAT efforts in the most compressed and stretched the rods of the truss are found.
