The Pressure distribution over a square wing tip on a biplane in flight by
Richard V Rhode(
Book
)
5 editions published between 1930 and 1931 in English and held by 16 WorldCat member libraries worldwide
The results are given in tables and curves in such form that the load distribution for any lift coefficient within the usual range encountered in flight may be determined easily. They show that the shape of the lower tip has no influence on the load distribution over the upper tip and also that a simple end fairing on the square tip results in an appreciable reduction of tip load extending inboard a distance equal to about 40 percent of the chord length. The reduction in tip load is accompanied by a simultaneous forward shift of the center of pressure on the same part of the wing

Eugene E Lundquist(
Book
)
4 editions published between 1932 and 1933 in English and held by 8 WorldCat member libraries worldwide
This report is the first in a series presenting the results of strength tests on thinwalled cylinders and truncated cones of circular and elliptical section; it comprises the results obtained to date from torsion (pure shear) tests of 65 thinwalled duralumin cylinders of circular section with ends clamped to rigid bulkheads. The effect of variations in the length/radius and radius/thickness ratios on the type of failure is indicated, and a semiempirical equation for the shearing stress at maximum load is given

Generalized analysis of experimental observations in problems of elastic stability by
Eugene E Lundquist(
Book
)
4 editions published in 1938 in English and held by 7 WorldCat member libraries worldwide
A generalized method of analyzing experimental observations in problems of elastic stability is presented in which the initial readings of load and deflection may be taken at any load less than the critical load. This analysis is an extension of a method published by Southwell in 1932, in which it was assumed that the intial readings are taken at zero load

A Method of estimating the critical buckling load for structural members by
Eugene E Lundquist(
Book
)
2 editions published between 1939 and 1940 in English and held by 7 WorldCat member libraries worldwide
The solutions of six simple problems are included to illustrate the application of the method of estimating critical loads and to reveal certain characteristics of the method that should be known by the practical engineer using it. Four of these problems are concerned with members that lie in the elastic, or longcolumn, range. The other two problems are concerned with memberes that lie in the shortcolumn range

Local instability of symmetrical rectangular tubes under axial compression by
Eugene E Lundquist(
Book
)
3 editions published between 1938 and 1939 in English and held by 7 WorldCat member libraries worldwide
A chart is presented for the coefficient in the formula for the critical compressive stress at which crosssectional distortion begins in a thinwall tube of rectangular section symmetrical about its two principal axes. The energy method of Timoshenko was used in the theoretical calculations required for the construction of the chart. The deflection equation used in this method was selected to give good accuracy. The exact values given by solutino of the differential equation were calculated for a number of cases and it was found that the energy solution was correct to within a fraction of 1 percent

A Method for determining the column curve from tests of columns with equal restraints against rotation on the ends by
Eugene E Lundquist(
Book
)
3 editions published in 1943 in English and held by 6 WorldCat member libraries worldwide
The results are presented of a theoretical study for the determination of the column curve from tests of column specimens having ends equally restrained against rotation. The theory of this problem is studied and a curve is shown relating the fixity coefficient to the critical load, the length of the column, and the magnitude of the elastic restraint. A method of using this curve for the determination of the column curve for columns with pin ends from tests of columns with elastically restrained ends is presented. The results of the method as applied to a series of tests on thinstrip columns of stainless steel are also given

Principles of moment distribution applied to stability of structures composed of bars or plates by
Eugene E Lundquist(
Book
)
6 editions published between 1943 and 1945 in English and held by 4 WorldCat member libraries worldwide
The principles of the cross method of moment distribution, which have previously been applied to the stability of structures composed of bars under axial load, are applied to the stability of structures composed of long plates under longitudinal load. A brief theoretical treatment of the subject, as applied to structures composed of either bars or plates, is included, together with an illustrative example for each of these two types of structure. An appendix presents the derivation of the formulas for the various stiffnesses and carryover factors used in solving problems in the stability of structures composed of long plates

Tables of stiffness and carryover factor for structural members under axial load by
Eugene E Lundquist(
Book
)
4 editions published between 1938 and 1944 in English and held by 4 WorldCat member libraries worldwide
The tables of stiffness and carryover factor that were presented in NACA Technical Note No. 652 have been extended to include the stiffness of a member with the far end subjected to a moment equal and opposite to the moment applied at the near end. These tables are of use in solving problems in the stability of structural members under axial load as well as in the usual applications of the Cross method of moment distribution when the effects of axial load in the members are considered. The values presented are for structural members in which the cross section and the axial load do not vary along the length of the member. The interval between successive values of the argument is small enough to make interpolation unnecessary in engineering calculations

Column and plate compressive strengths of aircraft structural materials 24ST aluminumalloy sheet by
Eugene E Lundquist(
Book
)
5 editions published in 1945 in English and held by 3 WorldCat member libraries worldwide
Column and plate compressive strengths of 24ST aluminumalloy sheet were determined both within and beyond the elastic range from tests of thinstrip columns and from localinstability tests of formed Z and channelsection columns. These tests are the first of a series in an extensive research investigation to provide data on the structural strength of various aircraft materials. The results, which are presented in the form of curves and charts that may be used in the design and analysis of aircraft structures, supersede preliminary results published previously

Book
)
3 editions published in 1940 in English and held by 2 WorldCat member libraries worldwide
A long column continuous over three supports was tested to determine its critical load when the center support was given amounts of initial displacement. During each test the middle support was hinged so as to be free to move parallel to the column axis during buckling
