This paper studies the effect of changes in the cross-sectional area on the profiles of extensible cables supported at equal elevations at both ends and sagging under their own weight only. The exact nonlinear differential equations that describe the

The theory of the spatial elastica is generalized to include the effect of centerline compressibility, and this leads to a nonlinear boundary-value problem containing seven differential equations. An algorithm employing a shooting method with two mis

A continous, deterministic mathematical model is used to predict population distributions by age at any time, given the initial distribution and the variation of birth and death rates with age and time. Solutions are obtained on a computer using a se

An exact theory is used to analyze tie-rods with various types of elastic constraints. The resulting nonlinear boundary-value problem is solved numerically by a shooting method, and graphs are presented to show the effect of centerline extensibility

The writer's previous work on buckling and post-buckling of a column with axial strain is generalized by allowing the cross sections along the member to change size and shape during the deformation due to the Poisson effect. Only a rectangular cross

The shooting method, used previously by the writer to analyze frames, arches, columns, and tie-rods, is applied to cables. For any loading condition, including the weight of the cable itself, and for any strain-stress relationship, the method converg

For an environmental system described by a system of nonlinear first-order differential equations, the problem of achieving specified terminal conditions in a given time with a minimum expenditure of resources is considered. The initial conditions an

The nonlinear differential equations of growth proposed by Volterra (1931) are used as the basis for a dynamic model of ann-element system withp specified, terminal conditions andp missing initial conditions. The resulting two-point boundary-value pr

The question of how to fit a general cubic model of a multicomponent, interactive growth system to observed data is addressed. A multidimensional-polynomial type of regression analysis is used, with a least-squares criterion. By testing the scheme on
