SV201 – Forces in a Truss and Redundant Truss
This exercise module has the following properties:
- Assembly of both a Determinate and Indeterminate Truss Framework via various length members, detent pins and joint hubs
- Quick and easy assembly of members via special detent pins and joint hubs
- Up to 10 members possible in one joint hub
- Loading unit with spindle drive and universal load cell for force measurement
- Members suitable for use with both trusses
Description
All members are clearance-drilled at each end to allow the detent pins to engage freely in the joint hub.
The machined joint hubs are drilled with a circular pattern of holes for the detent pin connections. In each joint hub there are 10 holes so that scale divisions of 30° and 45° are possible.
The smallest angle spacing between two members is 30°. This enables up to 10 members to engage on one truss hub.
One member on each truss hub must be rigidly located in the joint hub via a drilled location hole. This is necessary in order to obtain a rigid, statically certain truss. Without this, the joint hub would itself become an additional member of the truss.
The external stresses are applied to the truss via the load cell assembly.
The experiment frame deforms under the force and the deflection of the frame can be measured.
The load cell assembly can be attached to the frame at any truss hub, it enables tensile and pressure forces of up to 400N to be applied and measured.
