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.

Equilibrium of Coplanar Force Systems Lecture Notes

Chapter 3

This chapter deals with the equilibrium of coplanar force systems and will provide a basic understanding of the concept of equilibrium and its applications. Topics to be covered include; Equlibrium Equations, The Free-Body Diagram, types of Supports, Equilibrium of a Concurrent Coplanar Force System, and Equilibrium of a Nonconcurrent Coplanar Force System

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.

Friction Lecture Notes

Chapter 5

Friction forces exist when two surfaces are in contact, and have a tendency to slide on each other. Two types of friction ; dry friction and fluid friction.  This chapter will deal with dry friction.  Topics to be covered include; Laws of Dry Friction, Problems Involving Dry Friction, Wedges, Square-Threaded Screws, Belt Friction, and Rolling Resistance.
