Motion Study
A Method for Increasing the Efficiency of the Workman

64 MOTION STUDY the greater the fatigue — with no accompanying gain in output. We have determined that a cutting-out hammer for brickwork should weigh, exclusive of the handle, 3.75 pounds, but that a hammer for drilling plug holes in granite, for making dog holes in heavy stone blocks, should weigh 4 pounds. The weight of units moved should be standardized. Example. I here is undoubtedly a certain sized load in a shovel that will enable a first-class man to accom- plish the largest output with his maximum effort. Taylor has found his weight to be 21.5 pounds. The size of shovels that should be used should therefore be desig- nated on the instruction card accordingly, and exactly 21.5 pounds should be the standard unit of weight of material shoveled. Summary This discussion of the variables of the surroundings, etc., is not detailed — because general discussion is self- evident, arid detailed discussion must be too specialized to interest the general reader. It is only necessary to call attention to the general laws, logical and psychological, which underlie these variables, and their effect on standardizing motions. Each student naturally applies these laws to his own field, and sees for himself the opportunities for further study and application.
