Every editable page on Wikibooks has an associated page history (sometimes called revision history or edit history), which is accessed by clicking the "history" tab at the top of the page. The page history contains a list of the page's previous revisions, including the date and time (in UTC) of each edit, the username or IP address of the user who made it, and their edit summary.

Using a history page

On a history page:
  • All past changes to the page in question are listed in reverse-chronological order.
  • To view a specific version, click a date.
  • To compare an old version with the current version, click cur.
  • To compare a version with its predecessor, click prev.
  • To compare two specific versions, tick the left-column radio button of the older version and the right-column radio button of the newer version, and then click the "Compare selected versions" button.
  • Objectives

    The theory of elasticity deals with the deformations of elastic solids and has a well developed mathematical basis. This course will deal with applied engineering aspects of the theory and will include :
  • Definition of stresses, strains, equilibrium and compatibility.
  • Derivation of the governing equations.
  • Solution of problems in plane stress, plane strain, torsion, bending.
  • Introduction to three-dimensional problems.
Vectors and tensors will be discussed and used to enhance understanding of the theory where necessary. The course intends to provide the student with the tools and an understanding of the use of vectors and tensors in describing the deformation and motion of elastic solids, the formulation of the governing equations using physical laws, and the solution of simple linear elasticity problems using various analytical techniques.
