Structures and AccessoriesSuspension Cable
This equipment is used for studying the inter-action between suspension cables and load measuring supports with uniform or non-uniform distributed load on the catenary cable. It is to be used with ST300 Universal Structural Frame (separately supplied).
A light roller chain (the cable) is held by two sprocket pulleys and a spring balance is connected to each end of the roller chain. Weight hangers are evenly placed along the roller chain whose length simulates a parabolic curve. Weights can be put on the load hangers to create symmetrical and non-symmetrical cable.

Structures and AccessoriesTension Coefficients
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).
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.

Structures and AccessoriesThree Dimensional Equilibrium
The equipment is used for studying the equilibrium of five concurrent and non-concurrent forces in a threedimensional 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 mirrors 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.
Instruction manual is also included.
