3/4 point and cantilever bending test

thingiverse

Bending tests are some of the oldest and widely used and are used to determine the elastic modulus, bending moment and flexural stress and strain. Using a 3 point, 4 point and cantilever bending test rig you can print at school, we have created a series of lesson plans used to guide students through the concepts of elasticity, bending moment, flexural modulus and then beam geometry and finally CAD and FEA Analysis. The lesson plans run through points in the NSW HSC Engineering Studies syllabus however they are also applicable to many other disciplines including physics and maths. The most up to date lesson plans can be found on the new School of Materials Science and Engineering website: https://www.materials.unsw.edu.au/study-us/high-school-students-and-teachers/lesson-plans. The .stl files are in the zipped folder. The remixes to Stefan's excellent design include: * shape optimised 3 point test rig for faster printing * includes a space for a ruler to determine deflection cheaply * 4 point applicator * a range of applicators to suit different sized samples * cantilever test rig allows cantilever tests * beam samples
