Introductory Problems
The Problem Library consists of twelve common types of problems commonly used to introduce the concepts of stress and strain. These problems types are
For each problem type, the routine includes typical questions asked pertaining to the structure, common variations (such as double shear or single shear), and a picture or sketch that describes the problem geometry. After the student clicks the Compute button, the routine prepares a detailed explanation of the approach that should be taken to solve the problem using the usersupplied input data and units.
The Beam and Strut routine is devoted to a group of problems commonly used to introduce concepts of stress and strain. These problems feature a beam that is pinned at one end and supported by a rod, post, or strut at the other end. Often, these problem specify bolt or pin diameter sizes and either single or double shear configurations at the connections. The student may be required to determine the capacity of the structure considering limiting conditions on normal stresses in the strut and shear stresses in the connections. A beam and strut problem in any configuration can be solved by this module.
