Universal Buckling Unit

The Universal Buckling Unit is a unit to demonstrate the concept of buckling for struts, that allow to determine experimentally the relation between the buckling load and the methods of support of the test bars, different thickness and different shapes of the test bars.

ATENG 12179 — Universal Buckling Unit

Bench-top unit with adjustable legs.

Anodized aluminum frame and panels in painted steel.

• The “ATENG 12179” unit is mainly composed of:
• Two porticoes:
  A 1 m height portico, where the test bars are placed. It is designed to accommodate
  bars of different height by using two pins. Besides, at the upper and lower parts
  there are special clamps to subject the bar to the desired methods of support.
  A 50 cm height portico, where the test bar will be subjected to load by turning a
  hand operated spindle, which will tend to elevate the lower support, so the test bar
  will be subjected to compression.
  Regulation nut and bubble level that will allow to equilibrate the horizontal lower ATENG 12179 Detail
  supports.
• Digital balance to measure the bar compression load:
• Range: 0 – 50 kg.
• Accuracy: 100 g.
• Weight: 2 kg.
• Dial gauge to check the bar flexion as the test bar is subjected to load:
• Range: 0 – 20 mm.
• Accuracy: 0.01 mm.
  Accessory to create disturbing load over the test bar, which consists of support and pulley.
• Set of test bars, composed of:
  Fifteen bars of rectangular section of different lengths and different methods of support.
  Fifteen bars of circular section of different lengths and different methods of support.
