STUDY OF CONTINUOUS AND INTERMITTENT CRANKING MOTION.

Crank radius, frictional torque, plan angle and direction of turning are known to effect the cranking time. Adequate prediction models incorporating these factors are not available to the designers of man-machine systems. Consequently a set of experiments were conducted using three levels of radius, three levels of torque, three levels of plane angle, and two levels of direction of turning for continuous as well as intermittent cranking. Five male and five female right handed subjects performed these experiments. The results indicated superiority of clockwise direction of turning. The effect of radius, torque, and plane angle were found to be significant. Furthermore, the prediction models for turning rate for continuous and intermittent cranking were developed.
