Combination of resistant bodies. Arranged that they compel the mechanical forces of nature to produce some effect or work. -With certain determinate motions - the term machine is usually referred to a complete product

- Combination of resistant bodies. Arranged that the motion of one compels the motion of the others. - It is used to transfer and modify motion.

It is a combination of resistant bodies capable of transmitting forces or carrying loads but having no relative motion between parts.

It is a structure that supports the moving parts and regulates the path, or kind of motion, of many of the parts. - may either be fixed to the earth or moving relative to the earth.

It is an infinitesimal part of a body represented on a drawing by a point. - A line on a body may be thought of as a series of continuous particles arrangin line

One whose component particles remain at a constant distance from one another. - It is assumed not to suffer any distortion by the forces that may act on it.

Piece of mechanism which causes motion.

Piece of mechanism whose motion is affected.

- one element envelopes/encloses the other element - the form of the element is geometrically identical - surface contact exists between two members

- the elements does not enclose each other - the elements are either in point or line contact

Exchange of the fixedness of an element with its partner

- is indicated by change in position - can either be absolute or relative - determined by the path - has direction and sense

When a point continues to move indefinitely in a given path in the same aense

When a point traverses the same path and reverses ots motion at the ends of such path.

The term applied to reciprocating circular motion. (eg. pendulum)

When the motion of a point is interrupted by the period of rest.

Is the time rate of motion of a point along its path, expressed in linear unitsper unit of time .

Is the time rate of turning a body about an axis ( and the rate it is changing direction), expressed in angular units per unit of time.

A moving particle continues to move in a straight line covering equal distances in equal intervals of time. - acceleration is zero - velocity is constant

The speed changes by equal amounts in equal intervals of time. - Acceleration is constant

When the acceleration of a moving object as a function of distance, velocity or time. - can be solved analytically or graphically

If given distance and time

If given acceleration and time.

A type of motion in which the acceleration varies directly as the displacement.

An arm rotating or oscillating about an axis.

Two cranks rigidly connected to each other on the same axis.

Angle less than 90 degrees

Angle more than 90 degrees.

A rigid piece which transmits force from one piece to another. - processes at least two nodes which are points for attachment to other links.

it consists a number of pairs of elements called links connected to each other by joints.

An interconnected system of links in which not a single link is fixed.

When one of the links in the chain is fixed.

It consists of two cranks attached to stationary piece at one end and connected to each other by a rigid rod or bar called connecting rod, coupler or floating link.

Is a special form of a four-bar linkage with slider in which the center line of the slot passes through the center of the shaft.

-Also call kinematic pairs. -Is a connection between two or more links. -Allows motion between the connected links

The number of inputs which needed to be provided in order to create a predictable output. The number of independent coordinates required to define it’s position.

A lower-pair joint reduces the mobility of a mechanism by ____________?

A high-pair joint reduces the mobility of a mechanism by ___________?

Kutzbach’s Equation of mobility

are linkages that do not behave behave as predicted by the Gruebler/kutzbach equation.

Is the process of choosing different links in the chain as frame.

Is relationship which predicts the rotation behavior of a four-bar linkage’s inversions based on the link lengths.

Class 1 Case ( Grash of linkage)

ground either link adjacent to the shortest

ground the shortest link

ground the link opposite the shortest

Class 2 Case( Non-Grash of Linkage)

Class 3 Case ( Special-case grashof)

A special case of grashof condition where in all inversions can either be double cranks or crank rockers because of the presence of ___________?

shortest link will fully rotate and the other link pivoted to ground will oscillate

input motion is duplicated at a remote locations

It is the creation of potential solutions in the absence of a well-defined algorithm which configures or predicts the solution.

refers to the definition of the proper type of mechanism best suited to the problem.

determination of the proportion (lengths) of the links necessary to accomplish the desired motion.

generation of one or more solutions of a particular type suitable to the problem and has a defined synthesis algorithm.

correlation of an input motion with an output motion in a mechanism.

control of a point in the plane such that it follows some prescribe path.

Control of a line in the plane such that it assumes some prescribed set of sequential positions.

suitable for situations in which grashof crank rocker is desire

-two positions of a line in the plane are defined as the output. - will frequently result to a triple rocker mechanism

two positions with complex displacement

is a point, common to two bodies in plane motion, where in the absolute instantaneous velocity in each body is the same. Also called “centros” or “poles”.

it remain in the same place for all configurations of the mechanism.

it move when the mechanism move but the joints are of permanent nature.

it vary with the configuration of the mechanism

for a mechanism containing n number of links,

Any three bodies in plane motion will have exactly three instant centers, and they will lie on the same straight line.

-rate of change of velocity in direction-sense -perpendicular to the velocity of the particle at the give instant.
