HST5 Two Hinged Parabolic Arch

HST5 Two Hinged Parabolic Arch

The steel Parabolic Arch with uniform cross section has a span of 1.0metre and a rise of 0.2metre. One end is pinned in precision bearings set in a fixed springing attached to the HST1 Universal Frame and Stand (sold separately). The other end has bearings running on a track plate to which is attached an integral load cell for measuring the horizontal thrust created when the arch is loaded. The horizontal thrust is created by applying loads on the arch via seven equi-spaced load chains and hangers vertically suspended from the arch.

For model analysis measurements, pins are set on the arch at each load hanger. A dial gauge on a moveable stand is also provided for this work. The load cell and dial gauge output must be fed into the HDA200 Interface (sold separately).

A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.

Essential accessories: HST1, HDA200
