A statically determinate structure is
one where there is only one
distribution of internal forces and
reactions which satisfies equilibrium.
In a statically determinate
structure, internal forces and
reactions can be determined by
considering nothing more than
equations of equilibrium.

In other words, If a structure can be
solved by equations of statics alone, it is
said to be statically determinate.
Reactions and internal forces can be
determined solely from free-body
diagrams and equations of equilibrium
8. statically determinate structures of the
following types:
(1) pinned and rigid-jointed frames;
(2) stiffened shear webs ;
(3) thin-walled beams and torque tube
