Performance, Wrist Motion and Subjective Rating for Handle Angle of Pliers

摘要: This study aims to investigate the effect of handle angles pliers on performance, wrist motion and subjective rating satisfaction. An experiment was conducted, in which angle used as independent variable 14 subjects participated. Based literature survey, plier handles angled at 0°, 10°, 20°, 30° 40° were adopted experiment. The instructed bend iron plates by 90° cut wires soon possible. results revealed that 1) have significant satisfaction(p<0.0001); 2) did not affect performance completing tasks irrespective types done study; 3) initial stage windup, with 20° produced least deviation task bending plates, while cutting wires; 4) degree satisfaction maximized when bent both tasks. On basis results, it is recommended be 20~30°
