Features
Tesca Plastic Bending of Beams Apparatus provides two end supports; one for  completely rigid end fixings, whilst the other giving horizontal travel. Both supports create simple  supports (knife edges) and have clamp plates which create fixed ends by restricting the end rotation  of the test beam. 
 
The test beams have a single point load applied using the fine screw jack mechanism with integral  load cell supplied. The displacement of the test beam within its elastic and plastic regions is  measured using a dial gauge and this along with the load cell output connect into the optional  Interface.  

A set of black mild steel beams can be supplied with further sets available.
A comprehensive instruction manual for lecturer and student, giving full details on apparatus  assembly and operation as well as example results. All necessary assembly and operational tools are  provided.
