WP 300.04 Bending Device
Education / GUNT Hamburg / Engineering Mechanics and Machine Elements / Properties of Materials /

Using this accessory for the universal material tester WP 300, a bending bar is investigated. This is mounted on two supports and loaded with a point force generated by the tester. By sliding the bearing it is possible to apply the force in different positions and change the support width. An I-section steel beam is used as the base. This is straightforwardly bolted to the lower cross-member on the WP 300. Using the apparatus, the relationship between load and elastic deformation can be demonstrated. The influence of the modulus of elasticity and planar moment of inertia is also demonstrated.
