Eccentric Load Column Apparatus for Southwell Plot

偏心受压柱试验装置(Southwell 图法)

Real columns are never perfectly straight or centrally loaded, which is exactly what this apparatus demonstrates. Steel columns of 500 and 700 mm are loaded through knife-edge ends at eccentricities from 0 to 10 mm, up to 600 N via a lever. Two 0.01 mm dial gauges record lateral deflection, giving clean data for the secant formula and Southwell plots.

Product Description 产品描述

Real columns are never perfectly straight or centrally loaded, which is exactly what this apparatus demonstrates. Steel columns of 500 and 700 mm are loaded through knife-edge ends at eccentricities from 0 to 10 mm, up to 600 N via a lever. Two 0.01 mm dial gauges record lateral deflection, giving clean data for the secant formula and Southwell plots.

Highlights

  • Eccentricity 0 to 10 mm in 2 mm steps
  • Columns of 500 and 700 mm
  • Lever loading up to 600 N
  • Two 0.01 mm dial gauges

Applications

  • Secant formula verification
  • Southwell plot for critical load
  • Effect of initial eccentricity
  • Imperfection sensitivity teaching
