Horizontal reactions are monitored using the integral load cell within the track plate and its output fed into the Interface Deflection of Frame and sway is measured using the dial gauges supplied.
A 'rectangular' Portal frame and an 'S' frame made from rectangular solid steel section are provided with a range of fixed or pinned ends and simple supports to enable each frame to be set up in the Universal Frame and Stand and loaded horizontally and vertically.
Load hangers, calibrated weights, cords and pulleys are provided to apply vertical and/or horizontal loading to the frames. One end of the portal frame pivots on a knife edge, while the other end is free to move horizontally on a track plate against a load cell.
Experimental Capabilities:
Study the load, horizontal reactions, deflections, sway in portal frames
Comparison of experimental results with theoretical values derived using Castigliano's theorem and numerical analysis by Simpson's rule.
Deflection Of Frames Computer InterfaceThe Deflection Of Frames Computer Interface set has the same accessories as except Moment Support is replaced by Moment Load Cell Horizontal Force Support is replaced by Horizontal Force Load Cell Dial Indicator is replaced by Digital Indicator.
Software is included.
Two steel beams are supplied, each having a different thickness, thus allowing the effect of beam thickness and length on deflection to be studied. Two movable vertical beam supports allow the fixing of knife-edges to their tops to create a simply supported arrangement for the study of Deflections of Beams. Each support can be moved anywhere within the working area of the Universal Frame and Stand and allows a variety of beam spans to be achieved. Apart from the large difference in second moments of area (nearly 1 to 4.5) it will be found that the stiffer beam is more accurate experimentally, while the more flexible beam exaggerates the deflected shape and is visually instructive.
Each clamp can be positioned anywhere along the working length of the beam, and can be quickly and easily removed and re-positioned. A set of calibrated test weights and load hangers creates the loads. Three load hangers supplied ensure a variety of loads can be applied to the Deflections of Beams. Each hanger is attached to the beam via beam clamps.

The starter is equipped with thermal protection facilities, a start-stop push-button station and two pilot lamps indicating respectively the supply and the run state of the motor driven. The Delta Reduced Voltage Starter 60 HZ is used to start a motor having its six windings connected in wye for reducing voltage and in delta for increasing it. It is housed in a half-size totally enclosed portable modular unit. Connections to the unit are made through 4 mm standard color-coded, five-way binding posts. The trainer is protected by a either a diode or thermal-magnetic circuit breaker. Requires a 120/208V 60Hz circuit. This permits the utilization of banana-type jumper leads between the power supply and other components in the circuit. Specifications and/or diagrams are silk-screened on the back of a clear-plastic front panel for ease of identification.
