Two-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

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 AccessoriesArea Moment Method
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).
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.
Instruction manual is also included.
