A steel rod (20 mm diameter) 500 mm long is connected to two parallel aluminum rods (15 mm diameter) each 300 mm long via a rigid plate as shown. Two 70 kN loads at applied at the end of each aluminum rod. The structure is fixed at both ends resulting in a statically indeterminate system that can be treated as the superposition of two determinate systems as presented above. Note that Rc is the reaction at C. Assume Esteel = 200 GPa and Ealuminum = 70 GPa. a) Determine the reaction force at C, Rc b) Determine the reaction force at A and B and the normal stress in the steel and aluminum rods c) Which rods are in tension and which are in compression?

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.
