Equilibrium and Support Reactions

Civil engineers deal with structures that are composed of several members connected or with individual members such as beams and columns. To analyze such structures, the condition of statics must be applied. Under the static condition, the members are considered to be in equilibrium under the action of forces, that is, the members are assumed to be having negligible velocity.

Question

A) draw the free body diagram to prove its statically determinate and find the reaction forces at external supports

B) Draw internal force diagrams (axial force-N, shear force-Q and bending moment-M) and justify how values are obtained at critical points.
