SPECIFICATION

The object of Tesca Bending & Torsion Apparatus is to determine what levels of  combined bending and torsion cause elastic failure in different materials, and to compare them with  various theories of failure. The apparatus uses specially machined ‘necked’ specimens which are  clamped at one end to the base plate and at the other end to a counterbalanced circular loading  plate. Regular interval graduations on the loading plate allow a special hanger to locate. The special  hanger enables pure bending, pure torque or a combination of both to be applied depending on the  position of the hanger. The specimen deflection is measured by a dial gauge mounted diametrically opposite the load point. A set of calibrated weights is supplied along with a set of test specimens.  Further test specimens are available separately.

The object of this experiment is to determine what levels of combined bending and torsion cause  elastic failure 
In different materials, and to compare them with various theories of failure. The apparatus uses  specially machined specimens which are clamped at one end to the base plate and at the  other end to a counterbalanced circular loading  plate.  

 

Experiment Possibilities

  1. To determine elastic failure of a specimen subjected to several ratios of bending and torsion  simultaneously  
  2. To compare the results with the established theories of failure
