• The diagrams must be compatible with external constraints (i.e., moment equal to zero in the hinges or at free ends, shear equal to zero at free ends. . . ) • If shear T(z) is zero, moment M(z) presents a maximum or a minimum • If q(z) is zero, shear T(z) presents maximum or a minimum • If p(z) is zero, axial force N(z) presents a maximum or a minimum • The second derivative of M(z), i.e., the concavity, is −q(z)
