Training in hammering from the Russian Central Institute of Work and its Methods and Means for Training Workers. Management engineering : The Journal of Production (New York) 4 , no 4 (april1923), 243. This photograph documents a typical training exercise at TsIT-in this case , a worker being instructed by a mannikin in the art of hammering. The mannikin's two left arms demonstrate the correct posture of the arm relative to the body at the start and conclusion of its swing. Mannikins, templates, jigs, training frames, and photo-cyclograms are often used at TsIT in the construction of unskilled workers in correct body postures and work motions.
