Design Blueprint: Sliding Door Bar
Year: 2026
Type: article
Abstract: Design blueprint derived from the source paper (DOI 10.5281/zenodo.24121699): A length of timber dropped into the track of a sliding patio door is among the cheapest security devices sold, and among the least specified: dowels are bought by eye, in diameters that vary by a factor of two. This study computes the buckling load of a 0.9 m pine dowel from the Euler relation with a stated elastic modulus of 9 GPa, and compares it with a stated forcing load of 2,600 N at which the door's rollers and track begin to deform. A 25 mm dowel buckles at 2103 N, below the forcing load, so the door's own hardware is not the weakest element; the bar is. The buckling load reaches 2,600 Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
