Equilibrium 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.
TYPICAL EXPERIMENTS
- Equilibrium of a set of forces acting in a vertical plane
- Equilibrium of concurrent and non-concurrent forces

Structures and AccessoriesRedundant 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 AccessoriesTwo Hinged Parabolic Arch, Fixed End
This equipment is used for measurement of horizontal thrust and end fixing moments of the abutment for comparison with model analysis and simplified theory. It is to be used with ST300 Universal Structural Frame (separately supplied).
A parabolic arch has one end pivoted on a moment support and fitted with an arm for applying and measuring moments and rotations. The other end is pivoted in ball bearings on a horizontal force support. Load hangers and weights are attached to the arch. Load hangers are used for measurement of horizontal thrust and fixing moment.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Demonstration of the characteristics of a fixed arch
- Examination of the relationship between applied loads, horizontal thrust and fixing moment
- Comparison of behavior to simplified theory
