12 When the support reactions can be determined from the equations of statics alone, the beam is called statically determinate , such as Figs. 8-8 a , b, and c . Conversely, if the equations of equilibrium are not sufficient to determine the support reactions when the beam has more supports than are necessary to maintain the equilibrium, the beam is called as statically indeterminate, such as Figs. 8-8 d , e, and f . After the support reactions have been determined by using the equilibrium equations, internal forces transmitted by an arbitrary transverse cross section of the beam can be determined. This is done by passing a plane through the section such that the beam is separated into two parts, as shown in Fig 8-9 a . Each part of the beam separated by the section must also be in equilibrium under the action of the internal forces, as shown in Fig 8-9 b .
