NICATION MALFUNCTION
Typically, when the software is unresponsive or if it isn’t able to communicate with the
arduino it will return an error like the following:
could not open port ’com8’: FileNotFoundError(2, ’The system cannot find the file speci-
fied.’, None, 2)
It can be solved by first shutting down the software and unplugging/replugging the USB
connected to the Arduino from either the Raspberry Pi or the Computer used for operation.

Why do I need
Anaconda Distribution?
What is
Anaconda Distribution?
Then what is Miniconda?
Will it work on
my machine?
Quick install it
Get your conda cheat sheet
Take the test drive
Installing Python in a terminal is no joy. Many scientific packages require a specific version
of Python to run, and it's dicult to keep them from interacting with each other. It is even
harder to keep them updated. Anaconda Distribution makes getting and maintaining
these packages quick and easy.
It is an open source, easy-to-install high performance Python and R distribution, with the
conda package and environment manager and collection of 1,000+ open source packages
with free community support.
It’s Anaconda Distribution without the collection of 1,000+ open source packages.
With Miniconda you install only the packages you want with the conda command,
conda install PACKAGENAME
Example: conda install anaconda-navigator

ASTM Methodologies
NOTE: Information directly extracted from ASTM D256
Refer to ASTM D256 for more in-depth details.
4.1 MEASURING EFFECTIVE WEIGHT OF THE HAMMER
Swing the pendulum to a horizontal position and support it by the striking edge in this
position with a vertical bar. Allow the other end of this bar to rest at the center of a load
pan on a balanced scale. Subtract the weight of the bar from the total weight to find the
effective weight of the pendulum. The effective pendulum weight should be within 0.4%
of the required weight for that pendulum capacity. If weight must be added or removed,
take care to balance the added or removed weight without affecting the center of percussion
relative to the striking edge. It is not advisable to add weight to the opposite side of the
bearing axis from the striking edge to decrease the effective weight of the pendulum since the
distributed mass can lead to large energy losses from vibration of the pendulum.
May 7, 2018 63 of 66
4.2. MEASURING EFFECTIVE LENGTH OF THE HAMMER
4.2 MEASURING EFFECTIVE LENGTH OF THE HAMMER
The distance from the axis of support to the center of percussion may be determined experi-
mentally from the period of small amplitude oscillations of the pendulum by means of the
following equation:
L=(g/(4π2)p2
where:
L = distance from the axis of support to the center of percussion, mor (f t)
g = local gravitational acceleration (known to an accuracy of one part in one thousand),
m
/
s2
or (f t/s2), π=3.1416 (4π2=39.48)
p = period,
s
, of a single complete swing (to and fro) determined by averaging at least 20
consecutive and uninterrupted swings. The angle of swing shall be less than 5 degrees each
side of center.

4.3. SPECIMEN FAILURE TYPES
4.3 SPECIMEN FAILURE TYPES
The type of failure for each specimen shall be recorded as one of the four categories listed as
follows:
1. C = Complete Break: A break where the specimen separates into two or more pieces.
2.
H = Hinge Break: An incomplete break, such that one part of the specimen cannot
support itself above the horizontal when the other part is held vertically (less than 90¡r
included angle).
3.
P = Partial Break: An incomplete break that does not meet the definition for a hinge
break but has fractured at least 90% of the distance between the vertex of the notch and
the opposite side.
4.
NB = Non-Break: An incomplete break where the fracture extends less than 90% of the
distance between the vertex of the notch and the opposite side.
