The educational unit of deformation of trusses (ST – 008) is designed to determine the deformation of a single plane truss at one point using Castiglioni’s first theorem. The unit also allows to investigate the deformation of statically determinate trusses.

• The elastic deformation of trusses training system consists of the mounting frame in addition to the deformation of trusses kit and the weights kit.
• The truss being investigated is made of bars joined together by an articulated construction using node disks.
• The trusses can be considered as ideal trusses.
• The bars have special snap-lock fixtures on their ends to allow them to be fixed easily  into the node disks.
• The educational unit is provided with a load application device attached to a node disk generates an external force.
• The range of different bar lengths supplied with the educational unit permits three forms of truss to be constructed.
• The bars are made of PVC, so their deformations are clearly visible.
• All the component elements of the experiment are clearly laid-out and housed securely in a storage system.
• A cross arm is provided for lateral stability of truss
• The complete experimental can be setup on the mounting frame.
