Unsymmetrical Cantilever Apparatus — MOE Lab Tender Details

Unsymmetrical Cantilever Apparatus

Examines and displays bending of unsymmetrical cantilevers

Experiments
Investigations into bending of unsymmetrical cantilevers, including:
Vertical and horizontal displacement measurement for varying angles of applied load
Demonstration that maximum and minimum vertical deflection occurs when horizontal deflection is zero
Use of Mohr’s circle
Experimental and theoretical determination of the principal moments of area of test sections
Location of shear centre of each section

Specifications
Top Chuck holds the “fixed” end of the beam. Can be rotated through 360º in 22.5º increments
Bottom plate holds 2x Digital Dial Indicators
Set at 90º to each other to perform unsymmetrical bending experiments (Mohr’s Circle, second moments of area)
Set parallel for Shear Centre experiments (with extension piece)
0-25 mm (1”) range. Resolution 0.01 mm
Outputs to Versatile Data Acquisition System
Loads are applied with weights and hangers
Comes with 5x 10g weight hangers and 150x 10 g weights
2x Digital Indicators, each with a digital display and sockets for connection to the Versatile Data Acquisition System
Supplied with “Structural and Stress Analysis” textbook by THG Megson
