In tests of the strength of fishing gear and other marine equipment, the authors and other researchers have considered the viscoelastic behavior of fishing line, which has the simplest structure of all the components of fishing gear. This study presents a stress analysis of safety hooks was not only because they are an important item of safety equipment in seamanship training, but they are also widely used when working in high places. Of the several available procedures for stress analysis of photoelasticity, such as the Moire’ method, strain gauges, X-rays, photoelasticity was chosen because it allows visualization of the stress.
