To calculate fast remember it carefully.

THEORETICAL ARCH or LINEAR ARCH
Linear arch is an imaginary structure which is obtained by a funicular polygon for given arch which has all joint like a truss and loaded at joint only. All the members of theoretical arch subjected to axial comprehensive forces only and there is no shear force and bending moment in any member of theoretical arch.

EDDY THEOREM
If a linear arch is superimposed on a given arch then bending moment at any section on given arch is proportional to the ordinate of intersect between given arch and theoretical arch.
