Space Trusses: Problem Solving

A space truss is a three-dimensional counterpart of a planar truss. These structures consist of members connected at their ends, often utilizing ball-and-socket joints to create a stable and versatile framework. Due to its adaptability and capacity to withstand complex loads, the space truss is widely used in various construction projects.

Consider a tripod consisting of a tetrahedral space truss with a ball-and-socket joint at C.

If the height and lengths of the horizontal and vertical members are given, what force is acting on members BC and BA, considering that a tensile force is applied at D?
