Curved Bar and Ring Deflection Apparatus

曲杆与圆环变形试验装置

Strain energy and Castigliano's theorem make more sense once students see curved members deflect both sideways and down. This apparatus mounts five spring steel specimens, including a semicircle, quadrants, a 300 mm ring and a davit, on a 600 × 600 mm backboard. Two 0.01 mm dial gauges read horizontal and vertical movement under weights up to 20 N in 1 N steps.

Specimens
Semicircle, quadrant, quadrant with leg, circle, davit
Specimen material
Spring steel, 25 × 3 mm strip
Ring diameter
300 mm
Dial gauges
2 nos, 0–10 mm, 0.01 mm
