The branch of science that deals with motion, time, deformation, and forces
Forces: check things on how hard to push something to make it move or
whether it will break when we push.
Deformation and motion: check things to move or not move in certain ways.
Three major parts of mechanics
The mechanical behavior of objects and materials (constitutive laws)
The geometry of motion and distortion (kinematics)
kinetics)
Strength of materials expands statics to include material properties and
also pays more attention to distributed forces (traction and stress).
Strength of materials gives equal emphasis to all three parts of mechanics.
Kinematics concerns geometry with no mention of force
while kinetics concerns the relation of force to motion.
The distinct between kinematics and kinetics is that kinetics is concerned
with how forces interact with the motions of the system.
Kinematics of Machinery: a study of motion of the components and
basic geometry of the mechanism and is not concerned with the forces
which cause or affect motion. This study includes the determination of
velocity and acceleration of the machine members; the techniques of
mechanism synthesis.
Dynamics of Machinery: analyses the forces and couples on the
members of the machine due to external forces (static force analysis),
and also analyses the forces and couples due to accelerations of
machine elements (dynamic force analysis).
A rigid body means that the body resists deformation so strongly that
no deformation is allowed and thus the distance between any two
points that are attached to that body remains constant, regardless of
how the body is moved.
Similarly, the angle between any two intersecting lines that are
attached to a rigid body remains constant regardless of the motion of
that body.
System analysis: the investigation, under specified conditions, of the
performance of a system whose mathematical model is known
Analysis steps
Derive a mathematical model for each component in dynamic systems
Combine all the models to build a model of the complete system
Formulate the analysis results.
System design refers to the process of finding a system that
accomplishes a given task.
The design process is not straightforward and will require trial and error.
By synthesis, we mean the use of an explicit procedure to find a system
that will perform in a specified way.
The desired system characteristics are postulated at the outset, and then
various mathematical techniques are used to synthesize a system having
those characteristics.
Trial-and-error techniques are almost always needed, because the
features of the components may not be precisely known in practice.
