HSM10 Curved Bar

HSM10 Curved Bars

The theoretical deflections of curved shapes are most easily found by applying strain energy ideas, such as Castigliano's first theorem. The shapes chosen in this apparatus provide a relatively easy introduction to the use of such techniques. A bench mounted base supports a variety of curved bars in the form of a ring, semi-circle or quadrant/davit. Loads are applied by specially designed weight hangers so that the specimen bends. Horizontal and vertical deflections are measured by dial gauges rigidly attached to the base and surrounding pillars. The bars can be readily changed and the position of the dial gauges relocated to measure the deflections of the new configuration. All specimens, weight hangers and a set of calibrated weights are supplied.

  • To experimentally determine the vertical and horizontal deflections of various curved bars whose cross sectional dimensions are small compared with the bar radius.
  • To compare with theoretical estimates using strain energy theories such as Castigliano's first theorem.
