Tors i on of C i rcul ar Sect i ons STS6
Experiment for the study of torque and deflection in different materials with circular section. Mounts on the Structures platform and connects to the Structures automatic data acquisition unit and software (VDAS ® Onboard).
• Fully adjustable chuck positions for increased experiment range • Includes rods of different material for comparison of shear modulus (modulus of rigidity) • Includes a tubular (hollow) rod to show the effect of ‘missing’ material, compared to a similar solid rod L earn i ng Outcomes : • Torsion formula • Rod length and angle of twist relationship • Rod material and angular deflection— the elastic (shear) modulus ( G ) • Rod cross-sectional dimensions and torsion—the polar second moment of area ( J ) • Comparison of angular deflection in similar hollow and solid rods • Mass per unit length and torsional resistance efficiency of tubes compared to solid rods
