Öğe An analysis of sport managers' work stress levels in various variables(Horizon Research Publishing, 2018-12) Kılınç, Zühal; Dinçer, NevzatThis paper was conducted to measure the psychological and psychosomatic symptoms related with the sport managers’ work stress in public sector and federations. In this research, total 185 sport managers including 31 sport managers from the Central Organization of Sport General Directorate, 113 sport managers from the provincial organization, 41 sport managers from the Independent Sport Federations were included. The relevant managers were applied the work stress scale developed by Houso and Rizzo (1972). According to the results of the research, as sport managers get older, the averages of work stress seem to increase. In younger sport managers, the averages of work stress were found to be lower. When the participant sport managers’ education levels improve, their work stress points fall down. In the first period of service of sport managers, the averages of work stress were high, in next years they went down over time.Öğe The investigation of the tensile behaviors of single L-joint type bonded with adhesive and rivet(Wiley-Blackwell, 2018-08) Adin, Hamit; Kurtkan, Ümitn this study, tensile behaviour of single “L” type joints was investigated experimentally and numerically. Aluminium pieces with 2 mm, 3 mm and 4 mm thicknesses were used as joint materials. Overlap lengths were chosen as 10 mm, 15 mm and 20 mm. Joints were executed with two different rivets as steel and aluminium and 3 M 2216 epoxy based adhesive. Experiments were carried out by means of Shimadzu universal testing machine with 5 kN load cell. While the numerical study was carried out, using ANSYS Workbench, finite element analysis program, models were formed with the same properties as experimental works. Results showed that the samples with 20 mm overlap length had the highest strength of all models. Models with steel rivet had higher strength than models with aluminium rivets for all overlap lengths.Öğe The investigation of effect of adherend thickness on scarf lap joints(Wiley-Blackwell, 2013-10) Adin, HamitIn this paper, the mechanical behavior of the Scarf Lap Joints (SLJs) bonded with adhesive under a tensile load was analyzed. The effects of adherend thickness at the interface stress-strain distributions of SLJs were examined. The stress-strain analyses were performed by Finite Element Method (3D-FEM). The 3D-FEM code was employed with Ansys (Ver.12.0.1). Experimental results were compared with the 3D-FEM results and were found quite reasonable. It was concluded that both experimental and 3D-FEM failure loads were increased with increased adherend thickness. The results indicated that the maximum failure loads were determined at t=8 mm in all joints. The analysis of the SLJs under tensile load showed that the stress and strain concentrations occurred around the edges of the joints.Öğe Finite element analysis of safety pin in snowplow equipment(Hibetullah KILIÇ, 2022-06-30) Adin, Mehmet Şükrü; Adin, Hamit; Ergün, Raşit KoraySnow plow equipment is produced with chassis connections suitable for trucks, pickup trucks, tractors, construction machines and pick-ups and mounted in front of the vehicles. In this study, the stress and deflection values of the safety pin used in snow plow equipment will be examined by testing with finite element analysis. In this study, a damaged safety pin was analyzed numerically. The damaged safety pin was modeled with Solidworks package program and stress analysis was performed by ANSYS Workbench package program. In this analysis, the properties of the safety pin made of St37 steel were used. As a result , it was observed that the safety pin was damaged due to the stress distribution.
