The equipment demonstrates the use of tension coefficients in resolving three dimensional forces. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

A space frame is constructed from two tension members and one compression member. Each member has a built-in spring balance. The three members are joined together at an apex where a load is suspended. The other end of the compression member is a ball joint fixed to the bed and the other ends of the tension members have chains for attachment to two stationary columns. All joints can be slightly swiveled to minimize fixing moment. Resulting force for each member is measured by a three dimensions co-ordinate scale.

Instruction manual is also included.

The equipment is used for studying the equilibrium of five concurrent and non-concurrent forces in a three-dimensional system.

A rigid box frame has four swiveling pulleys at the top corners and leveling screws at the legs. Four cords, each with a load hanger outside the frame, pass over the pulleys and meet inside the frame concurrently or non-concurrently with an additional cord between two joints. A vertical load with a cord is applied at one of the joints. Each cord is marked out a 100 mm length. Two PVC sheet are attached on two adjacent side walls and transparent plates with transparent graph grids are attached on the other two side walls.  By aligning each marked cord to the mirror, its coordinates in space can be measured.
