Redundant Truss
The equipment allows measurement of deflections and axial forces in pin-jointed truss members when a redundant member is added. It is to be used with ST300 Universal Structural Frame (separately supplied).
A wall mounted truss frame has a pinned upper joint and the lower joint a roller bearing on a support. There are 7 truss members and an extra member with an adjustable length. Load is applied by a load hanger and weights. Deflection is measured by a dial indicator. Each truss member has a strain gauge which is wired to form a full bridge with temperature compensation and zero adjustment in the strain indicator.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Study of strains, stresses, forces and deflections in a statically determinate and indeterminate structure
- Force analysis by Method of Joints
- Force analysis by the use of the strain energy method.

Structures and AccessoriesEquilibrium of Forces
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).
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.
Instruction manual is also included.

Structures and AccessoriesTwo-Hinged Parabolic Arch
The equipment allows direct measurement of the horizontal component of the abutment thrust of a two hinged parabolic arch by using a simple model. It is to be used with ST300 Universal Structural Frame (separately supplied).
A parabolic arch of uniform cross-section has one end of the arch on a fixed hinged pin and the other is on bearings on a horizontal force support.
The horizontal movement of the roller end is monitored by a dial indicator. Measurement of horizontal thrust by the roller end is by using a pulley and a load hanger.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Demonstration of the characteristics of a two-pinned arch
- Examination of the relationship between applied loads and horizontal thrust
- Comparison of behavior to simplified theory
