Male torque strength in simulated oil rig tasks: the effects of grease-smeared gloves and handle length, diameter and orientation.
This paper examines the effects of two glove conditions and selected handle and task characteristics on tightening (clockwise) torques on cylindrical handles in simulated oil rig tasks. Ten males exerted MVC torques with the right hand on nine handles with different length-diameter combinations (3.8, 7.6, and 12.7 cm in length with 3.8, 6.7, and 8.4 cm in diameter) with dry and grease-smeared gloves in two orientations. The results showed a 50% reduction of torque when using grease-smeared glove compared to dry glove; a 15% increase with the long handle compared to the short one; a 25% increase with the medium diameter handle compared to the small one; and a 12% increase with the horizontally oriented handle compared with the vertical one. There were important interaction effects also.
