The equations of compatibility are written based on

In an I-section almost all the shear force is taken by

Plastic section modulus is defined as

Along the neutral axis of a simply supported beam

The ratio of stiffness of a member when far end is hinged to that of the member when far end is fixed is

When a rectangular beam is loaded longitudinally, shear develops

For finding forces in the members of a truss by the graphical method. The force diagram is suggested by

Modulus of rigidity is the ratio of

The shear force and bending moment are related by
