The main structural member of the wing is the wing spar or beam. It runs along the length of the wing from the fuselage to the tip of the wing. Some designs have one spar and some have two. They may be made of wood or metal. It depends on the construction. The wing with many spars is called a multispar wing. The function of the spar is to carry the main air load.
The ribs are attached to the spars. They run from the leading edge to the trailing edge. The ribs provide the shape of the wing and carry the loads. The skin covers the wing, hi case the akin carries the load it is called a stressed skin construction. The skin is supported by the stringers. They go parallel and between the spars and reinforce the skin.
