The measurements discussed in the preceding the paragraphs were taken on a 20-ft. column (NO. 8922) and^stresswas so small that little information could be gathered on theeffect of reapplication of load on the stress in the spiral. Todetermine the effect on the stress in the spiral of the droppingoff and the reapplication of the load, it was necessary to takereadings on shorter columns. So additional observations weremade on 5-ft. columns of the str
