Shear Center is to be used with Universal Base Frame or Universal Structural Frame. Interchangeable beam specimens are made from 1.2 mm steel sheet or approximate equal with welded-on end plates and a central loading plate which has a provision at the bottom for loading at different eccentricities from the beam axis. A load is hung at the bottom of the central loading plate and two dial indicators are used to measure deflections of both ends of the plate. The Shear Center equipment is used for studying the plane of traverse loading without twisting for selected standard sections. The end plates are attached to two flanged supports. The plane of zero twist is the plane of shear center.

Wrapped around the circumference of each step of the shaft is cord. At the ends of each cord is a single adjustable bob. The stepped shaft is secured to a main shaft, which itself is secured within a bracket. The bracket can be bench or wall mounted. Alternatively the starting position of each bob can be made different. The adjustment of the bobs can be made to ensure that the starting positions of each bob is the same even though the steps are different diameters.
Experimental Capabilities:
Compare actual results with theory
To find the relationship between angular rotation and the peripheral movement of the stepped shaft.
A bench-top unit for simulating the control systems installed in a building and studying the control and management of the various systems installed in a large industrial / commercial building.

The apparatus consists of a shallow water tight rectangular tank, approximately 2000 mm by 750 mm by 250 mm deep, which can be filled with a fine granular medium to form the experimental terrain. Valves control the number of spray nozzles in operation, enabling a moving storm to be simulated. Profile gauges and impermeable elements are supplied to allow the easy construction of sheet piling, walls, structures, foundations, reservoirs, bridge pier and dams, etc. Above the tank is a frame supporting an array of eight spray nozzles which are used to simulate rainfall. Washed silica sand graded 0.2 mm to 1.0 mm should be used as the permeable medium which must either be ordered separately from or supplied by the end user. Coarser material may be used. The tank is supported on a fabricated steel frame with mountings which allow adjustment of the inclination of the tank.
Experimental Capability:
Study of ground water abstraction through one or two wells
Simulated effects of civil constructions such as bridges and dams
Study of basin hydrological cycles
Permeability analysis
Study of flood and runoff hydrographs
Effects of surface storage on hydraulics
Fluvial process studies including:
Erosion by water on hillsides
Erosion in meandering rivers
Sediment transportation.

The stiffness of a spiral spring depends on its physical dimensions and the rigidity of the steel strip from which it is formed. With the Torsion of Spiral Spring Apparatus student can easily calculate the theoretical stiffness of the spring, and compare the value with simple experimental results. Spiral springs are used to provide a resisting or restoring torque to a shaft when it is rotated through an angular displacement. One end of the spring is attached to a shaft mounted in ball bearings. A load hanger and calibrated weights is used to incrementally load the spring. They exhibit similar stiffness characteristics to linear springs, except that the effect is one of torque rather than force. The wall mounted unit consists of a spiral spring coiled from a length of steel strip. Spring deflection is measured with an attached scale.
