초록
연근해 어업용 낚시 6가지형에 대하여 만능실험기로 인장속도를 290mm/min와 780mm/min로 하여 실험한 결과는 다음과 같다. 1) 낚시의 직경은 d, 미늘 기부에서 허리굽이까지의 거리를 w라 하면 낚시의 파단하중은
The fishing hooks were tested for breaking and unbending due to plastic deformation of the material. Study of tensile test is not complicated, but has not even worked out fully enough, especially when the test specimen is subjected to plastic deformation. The fishing hook is subjected to unbending stress and the critical section is a Point which is furthest from the line of action of the forces. The dynamic force of fish during jerks depends on their speed of movement and body weight, the kinetic energy corresponding to it and also on the rlastic displacement of the rigging which absorb the energy. Six kinds of hook were tested by the dynamometer under tensile speed 290mm/min (subscript s) and 780mm/min (subscript f). According to their results, the breaking load(B: kg) can be induced with the formula
