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.

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) for attachment of the accessories.

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. Load 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.

The equipment is used for verification of the deflections and slopes of a beam by area-moment method. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

The beam has a moment support and one built-in / knife edge support. The supports allow longitudinal travel of the beam. The moment support has a rotating arm which is monitored by a dial indicator. The moment is applied and measured by load on the rotating arm. The beam deflection is measured by a dial indicator.

This equipment is used for measurement of support reactions of a simple beam or cantilever in equilibrium under different loads.  It is to be used with ST305 Universal Base Frame or ST300 Universal Structural Frame (separately supplied).

The beam is supported by two weighing machines with knife edges fixed on to the pan. Load hanger with weights are hung on the beam between the two supports.  In the case of a cantilever, a spring balance and a weighing machine are used.

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.

Instruction manual is also included.

This equipment is used for studying the ground and wall reactions as a weight is moved up a rigid ladder. It is to be used with ST300 Universal Structural Frame (separately supplied).

A ladder with rollers at each end leans against a wall.  Reactions at both ends of the ladder are measured by nylon

cords tensioned by weights. A sliding weight can be clamped at any position on the ladder and the ladder is prevented from falling by a stirrup at the top.

Instruction manual is also included.

The equipment is used for studying the equilibrium of concurrent and non-concurrent forces in a single plane. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

Pulleys are fitted around the frame and multi directional forces are produced with nylon cords by weight hangers and weights. A graph paper (not supply) attached to the board is used for recording the lines of forces. Two rings cord for concurrent or non-concurrent forces and a device for marking the lines of the cords are provided.
