Radwin, Robert G., Oh, Seoungyeon and Fronzcak, Frank J. (1995): A Mechanical Model of Hand Force in Power Hand Tool Operation. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 548-552.

“A three-dimensional static equilibrium mechanical model of power hand tool operation was developed and used for comparing hand force associated with use of nutrunners having similar operating parameters (i.e. torque and feed force) but different physical parameters (i.e. shape, size, and mass distribution). The model used a Cartesian coordinate system relative to the orientation of the handle grasped in the hand using a power grip. Several important relationships between tool parameters and required hand force were revealed. Resultant hand force associated with different torque and feed force requirements were compared between four pistol grip nutrunners, and between pistol grip and right angle tools used for the same operation. Accessory handles and counterbalancers are also included in the model. Further development and validation of this model will be useful to power hand tool designers and tool engineers.”
