Flexural Effects in Disc Brake Pads

Details of the automobile disc brake are outlined, leading to the flexural requirements and construction of friction pad assemblies. A theoretical treatment of these is given, introducing the concept of a critical length which influences pressure distribution and reliability. A simple experiment which illustrates the critical length effect is described, with details of the experimental and theoretical correlation. The finite element technique is applied in a computer study of the structural behaviour of pad assemblies when subjected to various loads. Effects of load distribution, pad compression and backplate rigidity are discussed in the context of specific operational problems.

Micromeritics of Granular Pharmaceutical Solids II: Factors Involved in the Sieving of Pharmaceutical Granules

This report deals with basic studies concerned with the use of sieving as an accurate means of classifying granular pharmaceutical solids. Attention was focused on the effects of sieve shaker speed, initial load and particle size distribution of the granulation on the rate of particle size reduction and the cumulative per cent of material passing a sieve. The size and concentration of the smaller-than-mesh particles were shown to exert a profound influence on the equilibrium time of a sieve. Using a nest of sieves, an equilibrium time technique was developed to obtain the particle size distribution and permit calculation of various statistical parameters dependent on the observance of the log-normal law. An equilibrium time procedure such as developed here permits the quantitative classification of granular pharmaceutical solids by sieving, with a better assurance that separatio: has been achieved with the minimum of attrition.

Some Effects of Design Load Distribution on the Off-design Behaviour of Slender Wings

Summary:In order to trim a supersonic aircraft in the cruise condition it is often most efficient from the viewpoint of economic performance, for which a low drag is necessary, to use a cambered wing. The camber is designed to produce a chosen load distribution, but there is a wide range of suitable distributions. In view of this freedom of choice an investigation of the variation of Cm0 with design load has been made for a particular family of cambered delta wings. The calculations show that from the range of possible design load distributions it should be possible to choose one which results in Cm0 varying approximately in some desired way. Thus In principle It should be possible to choose a load distribution which satisfies the design requirements and results in improved off-design behaviour.

The Deflexion of a Thick Plain Ring under a Uniformly Distributed Couple

Several theoretical methods of estimating the deflexion of a thick plain ring under a uniformly distributed couple have been published, both in this country and in the U.S.A. Probably the best-known of these theories is that of Dr. R. W. Bailey.† In all cases the treatment has not been rigid from a mathematical point of view, the axial or shear forces in the ring notably being neglected, and the load being assumed concentrated on particular loading circles whereas in fact it is distributed over an appreciable area. The present paper attempts to treat the problem in a more rigid manner, with due consideration of the effect of load distribution. Expressions for the axial and radial deflexions, and the axial, shear, radial, and circumferential stresses in the ring are developed, and values of these functions are obtained for a wide range of ring dimensions, and are compared with the values of similar quantities obtained by the use of the theory of Dr. R. W. Bailey.
