Unit for Studying Free Vibration of a Bar Deluxe

The Unit for Studying Free Vibration of a Bar, allows the experimental study of the natural frequencies of the free vibration of a bending bar and according to Rayleigh’s method.

ATENG 12122 — Unit for Studying Free Vibration of a Bar

Bench-top unit.

Anodized aluminum frame and panels made of painted steel.

• The “ATENG 12122” unit mainly consists of:
• Bending test bar:
• Material: anodized aluminum.
• Length: 650 mm.
• Section: 20 x 3 mm.
  Two strain gauges of 120 Ω attached to the bar by a Wheatstone half-bridge configuration.
  Support to simulate the anchoring of the bar and to allow the variation and adjustment
  to the length of the bar.
  Hanger for the masses with knobs to fix the masses.
  ATENG 12122 detail
• Set of masses made of stainless steel: ten masses of 100 g.
  Two measuring rules, one horizontal and one vertical, to measure both the length of the bar and the initial amplitude of the motion.
  Two levels, each one installed on a rule, to guarantee the perpendicularity between them.
• Range of maximum amplitudes: ± 150 mm.
  Software for data acquisition.
• Electronic console:
  Metallic box.
  Connectors of the two strain gauges.
  Main switch.
  USB connector to the computer.
  Cables and accessories, for normal operation.
