Description
SE 110.16 Parabolic Arch Didactic Equipment Vocational Education Equipment Mechanical Training Equipment

Differences between statically determinate and statically indeterminate arches under load
Features
- statically determinate or statically indeterminate parabolic arch under load
- deformations of the arch under load
- bearing reactions of the arch
Learning objectives/experiments
- mechanical principles of the parabolic arch
- differences between statically determinate and statically indeterminate arches
- measurement of the deformations of the arch under load
- measurement of the bearing reactions on the statically indeterminate arch under load
- calculation of the bearing reactions
- influence of load on reaction forces and deformation of the arch
-- point load
-- distributed load
-- suspended elastic roadway under load
Specification
[1] investigation of a parabolic arch, optionally statically determinate (1 fixed bearing, 1 floating bearing) or indeterminate (2 fixed bearings)
[2] loading of the arch with a distributed load by way of 7 evenly distributed loads or by point loads or by suspended roadway with loads


[3] 2 dial gauges record the deformation of the arch under load
[4] weights to compensate for the reactions of a fixed bearing
[5] roadway with 1 set of shackles to be suspended into the arch; shackles in graduated length
[6] storage system to house the components
[7] experimental setup in frame SE 112
