Three Hinged Arch
This equipment is used for measurement of horizontal abutment thrust for symmetrical and unsymmetrical three hinged arch using a combination of concentrated and distributed loading. It is to be used with ST300 Universal Structural Frame (separately supplied).
The metal alloy arch is hinged at the middle with symmetrical and unsymmetrical spans. One end is hinged while the other has bearings on a horizontal force support with means of applying horizontal abutment thrust using a pulley and a load hanger. The center hinge has a needle roller bearing. A two-roller load and weights for uniform load distribution are provided.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Demonstration of the characteristics of a three-pinned arch
- Examination of the relationship between applied loads and horizontal thrust
- Comparison of behavior to simplified theory

Structures and AccessoriesEquilibrium of a Beam
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.
Instruction manual is also included.

Structures and AccessoriesUnsymmetrical Cantilever
The apparatus is used for studying a cantilever deflection and determining shear center when the plane of loading does not co-inside with the axis of symmetry of the cross section. It is to be used with ST305 Universal Base Frame or ST300 Universal Structural Frame (separately supplied).
The cantilever under test is mounted horizontally on a support column at one end. The mounted end can be rotated to indicate its position relative to a fixed angular scale. Load is applied through a weight hanger and weights at the free end. A circular disc is attached to the free end and vertical and horizontal displacements may be measured by two dial indicators. The pin where weight hanger is hung can be moved laterally on the circular disc across and outside the section of the cantilever to determine shear center.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Vertical and horizontal displacements vs angular positions for an applied load.
- Relationship between the vertical and horizontal deflections and the principal
- Determination of area moment of inertia around neutral axis.
