SYLLABUS

SYNOPSIS This course consist of three main component: Statics, Dynamics and SolidMechanics.

In Statics the students are introduced to vectors and forces and the usagein equilibrium of particles and rigid bodies. Students are also introducedto the concept of friction and the effects to a body.

In Dynamics the students are introduced to the concepts and theories ofkinematics and kinetics of particles and rigid bodies. In particular thestudents are introduced to analysis of forces and accelerations and also tothe principles of work and energy analysis, impulse and momentum andimpact analysis.

In Solid Mechanics, the students are introduced to stresses and strains,torsion and bending stress.

WHAT IS MECHANICS

Study of what happens to a “thing” (the technical name is“BODY”) when FORCES are applied to it.

Mechanics is defined as the field which studies the responseof the body to external excitation i.e. effects

Either the body or the forces can be large or small.

WHAT IS MECHANICS

Principles of mechanics applications in the applicationengineering (Vibrations - Bose suspension system, Lexusengine start and Volvo steering system, Stability and strengthof structures and machines, Robotics, Rocket and spacecraftdesign, Engine performance, Fluid flow, Electrical machines,Engine performance)

CLASSIFICATION

RIGID BODY MECHANICS



Only since machines and structures have operatedwith high speeds and appreciable accelerations has itbeen necessary to make calculations based on theprinciples of dynamics rather than on the principlesof statics

The rapid technological developments of the presentday require increasing application of the principles ofmechanics, particularly dynamics. These principlesare basic to the analysis and design of movingstructures


FUNDAMENTAL CONCEPTS

BASIC QUANTITIES

Length - is used to locate the position of appoint in space and therebydescribe the size of physical system.

Time - Time is conceived as a succession of events. Although theprinciples of statics are time independent, this quantity plays animportant role in the study of dynamics.

Mass - Mass is a measure of a quantity of matter that is used tocompare the action of one body with that of another.

Force - Force is considered as a “push” or “pull” exerted by one bodyon another. This interaction can occur when there is direct contactbetween the bodies, such as a person pushing on a wall, or it canoccur through a distance when the bodies are physically separated.







IDEALIZATIONS. Models or idealizations are used in mechanics in order

to simplify application of the theory. Three important idealizations.


IDEALIZATIONS.

Rigid Body. A rigid body can be considered as acombination of a large number of particles inwhich all the particles remain at a fixed distancefrom one another, both before and after applyinga load. This model is important because thebody’s shape does not change when a load isapplied, and so we do not have to consider thetype of material from which the body is made. Inmost cases the actual deformations occurring instructures, machines, mechanisms, and the likeare relatively small, and the rigid-bodyassumption is suitable for analysis.


IDEALIZATIONS.

Concentrated Force. A concentrated force represents the effect of a loadingwhich is assumed to act at a point on a body. We can represent a load by aconcentrated force, provided the area over which the load is applied is verysmall compared to the overall size of the body. An example would be thecontact force between a wheel and the ground.
