De f l ect i on of Beams and Cant i l evers STS4
Experiment for the study of beam deflection under different loads and fixing conditions, and the demonstration of Young’s modulus. Mounts on the Structures platform and connects to the Structures automatic data acquisition unit and software (VDAS ® Onboard).
• Selectable beam fixing conditions, with fully adjustable load and deflection measuring positions for increased experiment range • Includes beams of different material and cross-section for comparison of elastic (Young’s) modulus and Second Moment of Area ( I value) • High-resolution digital deflection indicator for maximum measurement accuracy
L earn i ng Outcomes : • Beam bending formula and structural ‘stiffness’ • Deflection due to point loads and UDLs (uniformly distributed loads) • How beam fixings affect deflection of:
– Simply supported beams – Fixed or ‘encastre’ beams
– Cantilever beams – Propped cantilever
• Shape of a deflected beam • Beam length and deflection • Beam material and deflection: the elastic (Young’s) modulus • Beam cross-section and deflection: the Second Moment of Area ( I value) • Pure bending of a beam • Reciprocal theorem (Maxwell-Betti)
