ST 01.2 – Frame Study

The objective of this equipment consists on the study of the deformation in the plane, of frame type structures under the action of solicitations. The equipment is supplied with a gantry in U and another with a “gable” roof.

Description

The equipment has a characteristic system of embedding and sliding articulated support.

The recorded deformation is extracted from the system by 2 comparator clocks that are placed at any point on the frame. These deformations are the response of the system to the different loads applied.

The loading of the structure is achieved through 2 load systems with weights, whose maximum load is 12 kg, having weights of different masses, from 0.5 to 2.5 kg.

Learning Objectives
  • Study of the deformation of frames in the U form and two waters.
  • Support study:
    • Embedment
    • Sliding articulated support
