Three-Pinned Arch

Experiment for the study of the characteristics of a three-pinned arch under various load conditions. Mounts on the Structures platform and connects to the Structures automatic data acquisition unit and software (VDAS® Onboard).

This product helps students to understand how loads affect the horizontal reaction forces in a three pinned arch.

Features

  • A simplified version of a realistic structure to give students an understanding of real-life structures
  • Includes multiple loads for many combinations of loads including uniformly distributed loads (UDLs)
  • Supplied with a storage tray to keep smaller items safe
  • Works with user-friendly software (VDAS®)

Learning Outcomes

  • Horizontal reaction due to a varying single point load on a statically determinate structure
  • Horizontal reaction due to a moving single point load on a statically determinate structure
  • Horizontal reactions due to a uniformly distributed load on a statically determinate structure
  • Influence lines and superposition
  • Lines of thrust in an arch
  • Graphical construction of a bending moment diagram for point loads
  • Maximum bending moments due to a load on an arch
