Parabolic Arch Apparatus with Digital Load Cells
数显测力抛物线拱试验装置
Reading thrust straight from a display removes the slow weight-balancing step and lets students check full equilibrium. This 1200 mm span parabolic arch with a 300 mm rise has four 0–500 N load cells at the springings, measuring horizontal and vertical reactions to ±0.1% FS. A 4-channel display reads 0.1 N, and a 0.001 mm digital indicator measures crown deflection.
