SE 110.17 Three-Hinged Arch Didactic Equipment Vocational Training Equipment Mechanical Training Equipment
Symmetric and asymmetric arch subjected to point, distributed or moving loads Features - statically determinate three-hinged arch - symmetrical or unsymmetrical arch - various load cases: point load, distributed load, moving load Learning objectives/experiments - familiarisation with three-hinged arches (unsymmetrical and symmetrical) - application of the method of sections and the conditions of equilibrium to calculate the support forces for -- point load, distributed load, moving load - investigation of the influence of the load on the horizontal thrust in the supports - determination of the lines of influence for the supports under a moving load - comparison of the calculated and measured support reactions for static and moving load Specification [1] investigation of 2 statically determinate three-hinged arches [2] hinged arch with 3 hinges: 1 crown hinge, 2 abutment hinges at the support points [3] 3 arch segments: 2x long (together making a symmetrical arch), 1x short (together with 1x long: unsymmetrical arch) [4] arch subjected to point load, distributed load (each by loads) or moving load [5] loads to compensate for the support reactions of an abutment hinge [6] storage system to house the components [7] experimental setup in frame SE 112 Technical data Aluminium arches - 2x long: 480mm, total arch length: 960mm - 1x short: 230mm, total arch length: 710mm - arch height: 250mm Weights - 4x 1N (hanger) - 36x 1N - 16x 5N - moving load: 10N+20N LxWxH: 1170x480x178mm (storage system) Weight: approx. 56kg (total)
