atethe effect of section on the modulus of elasticity. As wdiS done in the discussion of compression specimens,the final results have been stated in terms which do not dependat all on the shape of the test piece. The effect of the shapeof test piece has been eliminated. The remarlcable agreement of the results obtained underdifferent conditions of testing, has already been pointed out. 20. Coraoarison of Measured and Computed Results.-Tlie theoret-ical stresses in the arms of the three beams at each load -ere computed by the ordinary formulas and sumiuarized in TablesXIII, xrv and X7, pages 140, 141 and 142. It was assumed thatone-fourth of the load was carried by each reaction, and themoment was computed for a sir^gle arm. Prom the curves of averagedeformation on the arm a value of q called the computedvalue of q was deduced on the assumption that the ultimatedeformation of the concrete in the beam was about the same asthat in the control cylinder. The value of q used in computlirif^
