Abstract
According to the invention, an extendable member is disclosed. The extendable member may include a structure having a first state and a second state. The structure may be deformable between the first state and the second state. In the first state the structure may include a compact form. In the second state the structure may include a hollow longeron having a slit along the entire length of the hollow longeron. One or both longitudinal edges along the slit of the hollow longeron may have lateral protrusions. The lateral protrusions of a longitudinal edge may act in such a way with the other edge, and possibly its protrusions, to at least partially inhibit relative motion of the edges.
