Parabolic Arch Unit

The Parabolic Arch Unit, allows to study an isostatic (or statically determinate) parabolic arch (having one fixed support and one movable support) or a hyperstatic (or statically indeterminate) parabolic arch (having both supports fixed) under load, the deformations generated and the reactions of the supports of the arch.

ATENG 12154 — Parabolic Arch Unit

Bench-top unit.

Anodized aluminum frame and panels made of painted steel.

Main metallic elements made of stainless steel.

• The “ATENG 12154” unit mainly consists of:
  Frame with measurement system to level the ends of the parabolic arch.
  Parabolic arch made of tempered steel with seven cords with hangers to hang the weights
• from them (uniformly distributed load or point load):
• Length: 500 mm.
• Height: 200 mm.
• Cross section: 20 x 1.5 mm.
• Support systems:
  Fixed end.
  Movable end that moves horizontally along a guide. This end can be transformed into a ATENG 12154 detail
  fixed end.
• Three pairs of pulleys that allow to lodge the weights required for:
  To cancel out the horizontal displacement and to fix the movable support.
  To compensate the vertical reaction of the support.
• Two dial gauges:
• Range: 0 – 25 mm.
• Precision: 0.01 mm.
• Set of weights:
• Weights to apply load on the parabolic arch:
  7 hangers of 100 gr.
  7 weights of 100 gr.
  7 weights of 50 gr.
• Weights to compensate the reactions in the fixed support:
  4 hangers of 100 gr.
  13 weights of 100 gr.
  13 weights of 50 gr.
  Storage cage, with packing foam, for the weights and hangers.
