Results of tests of compressive strength, yield, etc, on various props of substitute materials; choice of material depends upon load carrying capacity; rate of yield, total yield, manner of failure under load, strength-weight ratio, strength-cost ratio, handleability, ease of setting, ease of withdrawal and suitability for repeated withdrawal; these are discussed in detail. (See also - n 4154 Aug 9 1940 p 129-31)
