Let C be a category with finite products and a terminal object 1. A list object over an object A of C is: an object L A, a morphism o A : 1 → L A, and; a morphism s A : A × L A → L A; such that for any object B of C with maps b : 1 → B and t : A × B → B, there exists a unique f : L A → B such that the following diagram commutes:
The slenderness ratio is an indicator of the specimen's resistance to bending and buckling, due to its length and cross section. If the slenderness ratio is less than the critical slenderness ratio, the column is considered to be a short column. In these cases, the Johnson parabola is more applicable than the Euler formula. [5]
The effective length is calculated from the actual length of the member considering the rotational and relative translational boundary conditions at the ends. Slenderness captures the influence on buckling of all the geometric aspects of the column, namely its length, area, and second moment of area .
Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events. [ 1 ] [ 2 ] In other words, measurement is a process of determining how large or small a physical quantity is as compared to a basic reference quantity of the same kind. [ 3 ]
A notice from the Chengdu Research Base of Giant Panda Breeding didn't identify the objects, but said that feeding pandas may cause them harm, and that the panda appeared to be in normal condition ...
A short steel column is one whose slenderness ratio does not exceed 50; an intermediate length steel column has a slenderness ratio ranging from about 50 to 200, and its behavior is dominated by the strength limit of the material, while a long steel column may be assumed to have a slenderness ratio greater than 200 and its behavior is dominated ...
Length contraction is the phenomenon that a moving object's length is measured to be shorter than its proper length, which is the length as measured in the object's own rest frame. [1] It is also known as Lorentz contraction or Lorentz–FitzGerald contraction (after Hendrik Lorentz and George Francis FitzGerald ) and is usually only noticeable ...
An empty list (), which is a special object usually called nil. A cons cell whose car is the first element of the list and whose cdr is a list containing the rest of the elements. This forms the basis of a simple, singly linked list structure whose contents can be manipulated with cons , car , and cdr .
