ASPECT

Of Earth Pressure

נו

In view of the important practi- cal aspect of matters relating to earth pressure on retaining walls, and earthworks generally, a con- siderable amount of attention has been given during the last half century to the development of a rational theory. Although the results of Rankine's examination of the subject have been widely used in practice. It has been re- cognised for some time that his theory fails to give practical re- 'sults in certain cases. Having in mind the composite nature of earth, it is manifestly, wellnigh impossible to formulate anything resembling a rigorous theory in the absence of a knowledge of the effect of the many factors in- volved in the problem. The most reliable experimental method, of approach Is therefore one in which as many as possible of the variables are eliminated from the investigation, such as would be the case with experiments involving the use of small model walls act- ed on by a material that does not 'Introduce scale-effects into the results. For example, clean Leighton Buzzard sand would form a suitable material for use In connection with tests on mo- del retaining walls. The data derved from experiments with such a material would, strictly speaking, be applicable only to cases involving similar granular materials, but the resulting infor- mation might well be used as a basis for further investigations, in which the material consisted of particles of various sizes,

CERTAIN ASPECTS

51

An examination of the subject -along these lines was initated by Professor C. F. Jenkin, in 1925, at the Invitation of the Earth' Pres- sures Committee of the British Association, and he presented cer- tain aspects of his results in a paper read before the Royal Só- ciety in 1931. In the following year, Professor Jenkin presented a contribution entitled "The Pres- sure on Retaining Walls" to the Institution of Civil Engineers, which was published in the Pro- ceedings, vol. 234, page 103. That paper dealt with the practical significance of the experimental results, and contained a full ac- count of the proof and verifics- tion of the resulting "revised wedge" theory of the author which is based on the assumption that a wedge of the material slips down behind the retaining wall us it moves forward. In order to facilitate the application of the theory to cases. of walls having any batter, the Department of Scientific and Industrial Research has recently published Earth Pressure Tables (HM Stationery Office, price 25: net), which con- tain the data necessary for cal- culating the pressure exerted by gramnular materials on retaining walls.

With the aid of these tabulated values, a minimum amount of la- bour is required to evaluate the related pressurès according to the theory, so that the publica- tion possesses a real value for éngineers engaged on the design of earthworks. It follows from the above remarks that this book should be on the shelves, of "every library connected with undertak ings in which work of this, har- acter is commonly carried out.

Keen Competition

For Order

Designers in several shipbuild- ing centres have been exceeding- ly busy of late preparing ten- ders for the most important shipbuilding order that will be places this year the aircraft carrier for the Admiralty's 1934 programme. There is keen com- petition for this order, And it

will not be an easy task for the Admiralty to decide where it will be placed. writes a correspon- dent.

I understand that Clyde, Tyne. Barrow, and Mersey Arms have all submitted tenders. Among these are three Clyde establish- ments, two of which have re- ceived no shipbuilding work for the 1934 programme.

Hopes are high on the North-" east of England that the order will be assigned to a Tyne-yard, but that is by means certain in view of the competition from the Clyde and other centres:

The projected " vessel, will cost about £2.500.000 will be. one of the largest aircraft car riers ever built. A large aircraft carrier was in ontemplation for the Navy Estimates of 1929-30, but the echstruction of the vessel was deferred for further experl- ence with the aircraft carriers in service. It is now believed that the construction of a vessel of this type cannot be much longer delayed. The order will mean

thousands employment for

of men for at least two and a half years.

In addition to the aircraft car- rler the only vessels that remain to be placed for the 1934 pro. gramme are one.or two small craft such as boom gate vessels. survey ships, etc.

ENGINEERING ORDERS Messrs R. and W. Hawthorn Leslie and Co., Ltd., Hebburn-cn- Tyce, have received the orders for installing the propelling ma- chinery in the two oll tankers which are to be constructed" by Messrs Swan, Hunter and Wigham... Richardson, Ltd., Wallsend, for the orders for the bulls were an- nounced about a fortnight ago it was indicated that, although the machttery would likely be built an the Tyne, it had not yet been decided which firm would build them. However, it was officially ascertained last week that Messrs Hawthorn Lesile, who built the engines for the Ancylus, which bas completed highly successtut trials, nad been entrusted with the work. The brder will be car- rled cup at their St. Peter's Works, Newcastle.

Mr. W. A. White, of White's Marine Engineering Company,

Ltd.. Hebburn-on-Tyne, has' re- ceived an order for the construc- tion of machinery for a trawler" for. North Shield owners, The machinery will be similar to that (except on a smaller scale) in- stalled in the Adderstone, which Mr. White claims is one of the - most economical ships in the world. The trawler itself will be of the streamlined type, with a new form of bow, and will be Atted with the latest trawling apparatus and modern wireless locating apparatus This will be first Hme Mr White's economy engine has been combined with a streamlined hull, and, following the results of the trawler's per- formance, he hopes to secure orders for similar machinery to work in conjunction with stream- lined cargo ships..

·J, C. McLennan, F.R.S., being in the chair. Proposing the toast of "The Association," Sir Frank Smith said that, compared with those who had to undertake in- vestigations on the subject of "fish. of which there were more

than 30,000 species, the lot o the electrical research worker was comparatively easy. There was only one electricty, and even so Industrial research workers were not much concerned with its na- ture. This was the right proced- ure so long as work in pure science was continued and so long as the assistance it could render to industry was recognised. It was axiomatic that no harvest arrived on the day the seed was sown, but at the same time t might be pointed out in how short a time the discovery of the elect- 'ron had become the basis of an industry with an annual turnover £20,000,000 The same was equal- ly true of the discoveries of neon argon and krypto

NOTES FROM BRITAIN

British Equipment For French Liner

The fatest challenger for the Blue, Riband of the Atlantic, the new "French"liner "Normandie. “ emerged from her tralls with conspicuous success, reparts stat¬ ing that a maximum speed of 33 knots was attained over a mea- sured distance. This quadruple- screw turbo-electric vessel pos- sesses a total length of 1029ft. 5 in, and a tonnage, of 78,000. · Re- cent Atlantic flyers, such as the "Bremen" and "Rex" are thus positively dwarfed.

It is particularly satisfactory to learn that several British' firms were concerned in providing equipment for this crack French vessel. including manufacturers of electric motors and the ex- tensive ventilating equipment in- stalled throughout the ship. It has been estimated that, the weight of fresh air drawn into the "Normandie" every hour for ventilating purposes reaches the huge figure of 3500 fors, while comprehensive exhaust sys- tem is also installed to balance the supply. The total horse- power of the motors employed in conjunction with the ventilating equipment alone is over 1500.

ACCIDENTS

The Principal Hazards

un

The writer of an article "Accidents to Minors in Call- fornia in 1932, says that ma- chines have often been regarded RS the principal industrial lazard and insufficient attention has been paid to other causes of accidents. The facts disclosed in the contribution, which appears m the Bulletin of the American Bureau of Labour, should serve it is claimed, focus attention upon vehicular accidents ance they show that vehicles con- stituted the

EXCELLENT BARGAIN Looking at the report of the As- sociation from the point of view of the ordinary individual It seemed that they had made an excellent financial bargain with the Government, and he was therefore surprised that the elect- rical industry had not yet fully implemented their part of the *** contract It was surely not too much to expect that this should be done without delay. In reply, the President said that the acti vities of the Association were all definitely associated with the so- lution of problems of vital inter- est to the electrical industry," and especially with those relating to the "gird" system and to the de- velopment of telephone COM- munication. When these were soi- ved attention might once more bé turned to the old problem of 1- lumination, with the result thas the position of the filament lamp might be challenged by those in which radiation was obtained by the use of arcs in various gases. In the field of radio trariamissión the progress that had been made during the last few years was...as-' tounding, but it would be a great .. boon when it was possible to make valves capable of emitting beams of waves as short as I mm. or less. The high-potential · ap- paratus that had been construct-the serious temporary disabilities

ed for atomic research was also being utilised for the production of X-ray of greater and greater Penetrating power, and these were being employed for medical and other purposes.

TO GENERATE CONNECT In this connection attention might be called to the proposal to generate electricity by enorm- ous discs spinning "in vacuo" and to transmit it along vacuum-sur- rounded rods. A generator of this kind operating at 10,000,000 volts direct-current had been con- structed in the United States and was being tested in connection with such an "airless" transmis- sion system. A project fut em- ploying this system in the Tennes see Valley was stated to be "plan- ned and ready to start." If BUC- cessful this, might have a pro- found effect on the transmission of large quantities or electrical energy over long distances
