Abstract
A SHORT general account has been issued by the City and Guilds College, Imperial College of Science and Technology, of researches in progress at the College which are mainly financed by an annual grant of the Clothworkers Company given to further engineering research. This research report for 1937-38 contains a brief account of the fluid motion research in the Department of Aeronautics. In the Department of Civil Engineering experimental work on the static loading of a 10-ft. span voussoir arch has been completed which has shown that the generally accepted method of design is unduly pessimistic since even lime mortar joints can resist some tensile stress, and with cement mortar the first sign of failure is at a considerably higher load than that given by the classical theory. An investigation of stresses in suspension bridges is in progress, and in addition to various structural researches the problems of river meander, tidal phenomena, wave research and tests of bituminous jointing compounds for liquid-retaining concrete structures have received attention in the Department. The Department of Electrical Engineering has constructed a high-frequency Wheatstone bridge and also a high-frequency Sobering bridge. Besides its work on heat transmission, the Department of Mechanical Engineering has been responsible for work on heat dissipation from surfaces by natural convection in gases and liquids, including mercury, on heat transfer from gases flowing through packed solids, radiation from non-luminous gases, convection in pipes at low velocities, evaporation and convection, gumming tests on lubricating oils with the Helmore-Griffiths oil-testing machine, the mechanical properties of metals near their melting-point and on internal combustion engines.
