Kinematics Flashcards
is the study of motion without
considering the forces that cause it. In machine
components, kinematics helps engineers analyze and
design mechanisms that control motion in machines
such as engines, robotic arms, and linkages.
Kinematics
Study of
motion (linear, rotational,
and general motion)
without considering
forces causing it
Kinematics
Assemblies of machine elements designed to
transmit motion
Mechanisms
A system of connected links that transfer motion and
force in a mechanism.
Linkage
A rule that determines whether a four-bar
linkage will have a continuously rotating link.
Grashof’s Law
A connection between two links that
allows motion (e.g., revolute, prismatic).
Joint (Kinematic Pair)
A point in a moving
body that has zero velocity at a given instant.
Instantaneous Center of Rotation (ICR)
The process of determining the position of
different links in a mechanism at a given instant.
Position Analysis
mechanism that converts
rotary motion into
reciprocating motion (e.g.,
in engines).
Slider-Crank Mechanism
The simplest movable closed-chain
linkage with four links and four revolute joints.
Four-Bar Mechanism
Change in position of a point or
body
Displacement
Rate of change of velocity
Acceleration
Rate of change of displacement
Velocity
Basic Kinematic Quantities

It is a fundamental concept in kinematics that
involves determining the exact location of key points
in a mechanism at a given instant. It helps in
understanding how different components of a
mechanical system move relative to one another. By
analyzing the position of links, joints, and points,
engineers can ensure proper motion, alignment, and
functionality of a mechanism.
