A new departure in the annals of the Institution was inaugurated at a meeting held on Thursday, April 28, 1927, in the Institution’s meeting hall, 10, Upper Belgrave Street,
S. W.l, when the problem of the education of structural engineers was debated. The President (Mr. H. J. Deane) was in the chair. The motion before the meeting-proposed by Professor J. Husband, M.Eng., M.In-st.C.E. (Member of Council), and opposed by Mr.
Ewart S. Andrews, B.Sc., M.1nst.C.E. (Vice-President)was :- “That the system of education of structural engineers by articled pupilage is contrary to the best interests of the student, and should be superseded by education in recognised engineering schools.”
When the paint is too thin the heavy particles of lead gravitate downwards, and so it happens that a thicker deposit is formed on certain parts of the surface by partial denudation of other parts, and if a suitable portion of paint skin cut from a vertical
painted surface were examined under the microscope this would be readily observed. The obvious remedy for this would be to fill the paint up with dryers so that the lead would not be given time to settle, which remedy is as bad, if not, worse, than the evil. If such paints are used it is at all times necessary to rub well into the surface inequalities of the metal and to use sparingly, since the adhesion of the first coat is of prime importance.
In the design of steel roof truss members but little consideration is usually given to the bending actions which often occur. The most important of these may be conveniently
grouped under the following heads:-
(1) Lateral loading on rafters.
(2) Eccentricity of riveting.
(3) Non-intersection of axes of members at joints.
(4) Rigidity of joints and deformation of truss under load.
