How to Use MATLAB
What is MATLAB
MATLAB is an interactive package for numerical analysis, matrix computation, control system design
and linear system analysis and design. On the server bass, MATLAB version 4.0 is available. In

Geometric tolerances are used for
Control of position of features within parts
Control of form or shape of features of specified portions of the part.
It appears here as if the maximum tolerance of the position of the h
HISTORY OF THREADED FASTENERS
No standardization of threads until 1841, therefore no interchanging of parts.
Sir Joseph Whitworth attempted to create the first standardized form of
threads in 1841 but was used in England and not in t
Used to prevent the rotation of pulleys, gears, etc., on their shafts.
A key is a piece of metal placed so that part of it lies in a groove, called the key seat, cut in a
shaft. The key than extends above the shaft and fits into a keyway cut in a hub
NEED FOR TOLERANCING
Tolerancing of parts allows control of dimensions and to imply a certain precision.
Controls the maximum and minimum sizes of parts for proper mutual fitting.
The desired tolerance can affect the tooling selecti
THEORY OF ORTHOGRAPHIC PROJECTION
A method to describe shape by the process of causing an image to be
formed by rays of sight taken in a particular direction from an object to a
If the rays are perpendicular to the picture pla
SECTIONAL VIEWS AND CONVENTIONS
1. PURPOSE OF SECTIONAL VIEWS
To see the inner details of an object.
Sectional views help in clarifying the interior shape of a part because in the outer
view too many hidden lines can create confusion.
To sometimes see sma
