Forces in a Simple Bar Structure Model MT 017

Sci-tech Forces in a simple Bar Structure Model MT 017 represents a simple bar structure. In the single
plane system the bars are only subjected to compression and tension. Loads are applied only to the nodes.
The unit comprises three members that are joined together using discs such that the joints are free to move. A
longitudinally adjustable bar permits the bar structure to be constructed with different angles. The bars engage
in the discs by snap-locks. Two of the node discs also form the supports (fixed and free) and are clamped to the
sturdy aluminum section base frame.
