Simple Stresses Lecture Notes

Chapter 9

Strength of materials is the subject of the relationships between the external loads on an elastic body and the intensity of the internal forces acting on the body.  Stress is defined as the intensities of the internal forces acting on the body.  The study of strength of materials will deal with the load carrying capacity of a member, the deformation characteristics, and the ability of a member to maintain its initial configuration. Topics to be covered included; Introduction to Strength of Materials, Normal and Shear Stresses, Direct Normal Stresses, Direct Shear Stresses, Bearing Stresses, Stresses on Inclined Planes, and Stresses in Thin-Walled Pressure Vessels.

Resultant of Coplanar Force System Lecture Notes

Chapter 2

Two systems of forces are said to be equivalent if they produce the same mechanical effect on a rigid body.  A single force that is equal to a given force system is called the resultant of the force system. Topics to be covered include; Vector Representation, Resultant of Concurrent Forces, Rectangular Components, Resultants by Rectangular Components, Moment of a Force, Varignon’s Theorem, Couple, Replacing a Force with a Force-Couple System, Resultant of a Nonconcurrent Coplanar Force System, and Resultant of Distributed Line Loads.

Analysis of Structures Lecture Notes

Chapter 4

A structure is a connected system of members designed to support loads and transfer forces.  To analysis structures we will look at the equilibrium of an entire structure, part of a structure, or an individual member.  This will included finding the external reactions as well as the internal forces.  Internal forces are defined as the forces required to hold the structure together. Topics to be covered include; External and Internal Forces in a Structure, Trusses, Method of Joints, Zero-Force Members, Method of Sections, Frames, and Machines.
