abstract = {It is the objective of this paper to present the highlights of the analytical method currently used to obtain optimum system worth of simultaneous minimum weight, minimum space envelope and maximum reliability for airborne and missile-borne electronic and electromechanical equipment.
The approach to achieving minimum weight and space and optimum maximum reliability is called Generalized Value Engineering. The typical Value Engineering concepts of reducing costs are generalized by mathematical relationships to determine governing stresses, buckling allowables, margins of safety, configurations and schemes for minimum weight and space with positive low numerical values for margins of safety. The structural racks were analyzed as complex frameworks Including Vierendeel truss action. Myklestad's notation and equations were used to determine the distribution of shears, bending moments, deflections and rotations throughout the framework. The modules supporting the racks were analyzed as truss-type members allowing for partial fixity at the joints.},

abstract = {While it is true that tabulating machines are more ideally adapted to grinding out our weekly pay checks, and the new larger electronic digital computers are replacing armies of people with desk-calculators, I do not pretend that machines can do anything like this for us. We will not be able to dispense with the services of a single weight engineer or computer, but it is quite unfair of our critics to say that machines are handicapping us.
The reason that our problem is not ideally adapted to machine methods is that the input data is not only extensive, but rapidly changing, and the output presentation is usually as extensive as the input. We have found that machines are suited to handling the weight work on a project from the time that the design has jelled enough to write a Group Statement. Many different reporting breakdowns are required during the project. All you have to do is to code the entry a sufficient number of ways and the rest is up to the machines.
This paper will describe the method that is used at Republic Aviation Corporation for weight reporting in use with the IBM Card-Programmed Electronic Calculator. I will describe the considerations that must take place in the setup, the lessons learned along the way in using the system, and future plans.},

abstract = {'The contractor shall provide for an adequate system of weight control' or similar wording is as familiar to aircraft weight engineers as the back of their hands. In a liberal sense, these few words are the justification of a weight engineer's existence. It follows that, for a weight engineer to function properly, it is a prime necessity to have some system that is flexible enough to encompass all possible designs and is broad enough to mesh into all design phases from inception to completion. The development of such a system, and the associated problems of maintaining it to keep pace with the ever increasing complexities of modern aircraft design, has consistently been a major problem in every weights group.
This presentation is made primarily in the hope that it will furnish impetus to the practical acceptance of applying card-punch methods, a modern concept, to the modern problems of weight control. It is, however, also made as an example of things to come so that procuring and manufacturing agencies alike may take note that future specification requirements must allow for cardpunch equipment application in so far as the form in which these requirements are to be met is concerned. The ability of present and planned electronic cardpunch machines to provide an almost unlimited variety of information in fantastically small time intervals is limited only by the imagination of man, but the practicability and cost savings of asking a machine to accomplish a task lies in allowing it to perform that task in the manner best suited for it. If our required end result is a home run, we wouldn't ask our clean up man to do it with a golf club although conceivably he might be able to do it. The scope of this paper is, however, not to suggest specific changes in current weight specifications; the time has not yet arrived when we know exactly what form the changes will take, but it draws near. It is enough now to realize that, if electronic card-punch equipment is invited to find its place in weight control, some consideration must be given to the conditions of the invitation.},

abstract = {This paper provides t quick outline of another method for using I.B.M. machines in engineering work.
To begin with, I want to disillusion those who believe that I.B.M. will in some miraculous way, do all of their work. The I.B.M. method of procedure provides a rather painless way of arriving at an accurate weight and balance report for experimental airplanes and for keeping a running weight and balance record during the life of the production contract. It is possible with this method to run off a detailed weight and balance calculation for any airplane of the contract in a matter of about six or eight hours. It also eliminates the drudgery of many hours of calculation and checking with their attendant mistakes. These hours saved can be spent to better advantage in weight control rather than in record keeping.},
