Machine Elements
ABSTRACT
Machine elements are the basic parts of machines. Since these parts are manufactured in
bulk, it is always cheaper to buy these parts than to manufacture them. Moreover, if pos-
sible, the designer should use machine elements to make servicing the machine easier in
the future. Some of the functions inside a machine, such as transmission of power or
reduction of speed, are a common challenge and can be easily solved with standard
machine elements. The standardization of the machine elements makes them easier to
use. The designer should learn both the functional difference and the standard of them.
For example, gears, belts, and chains can be used for the transmission of power, but they
have different advantages and disadvantages. Moreover, the designer should learn the
standard of the interested part. For instance, the calculations can point to a M9 size bolt,
but the standard sizes are M8 and M10. In this case, the M10 size bolt should be preferred
to carry the force.
