The
80/20 Deflection Calculator 





80/20's
Deflection Calculator is a stand alone in 95/98/NT/2000/XP program
that allows estimation of extrusion deflection solving for length,
load weight, or deflection. 80/20’s Deflection Calculator
also comes with a conversion calculator that provides calculation
cross
measurements.
The deflection of nonlisted bars can also be achieved by selecting
other from the extrusion list and entering the profiles values. 

























Using
The Deflection Calculator 





 Select Extrusion 
From the lists shown, select the extrusion for which you wish to
make calculations. (If you are performing a calculation for some
other beam, that
subject
is covered later.) You will find in the available extrusions both
Fractional and Metric. 1010 is the default extrusion selected, and
all labels are shown in fractional units. If you select a Metric
extrusion, the labels are shown in Metric Units.
 Select Moment 
Select which moment of inertia to use. The software assumes top loading,
and the graphic will indicate the orientation of the extrusion relative
to a top load. When you select a Moment of Inertia (Ix or Iy) the
Moment Data box will be populated with the appropriate moment of inertia
from the Extrusion Data list.
 Type of Load 
Select whether the load is a Point Load (assumed to be in the center
of the extrusion) or Evenly Distributed.
 Solve For 
Choose which value (Length, Load, or Deflection) you wish to solve
for based on the data that you have.
 Input Known Data 
Input the data you have into the appropriate boxes. 






Solution 
Pick the Calculate Button to perform the calculation with the data
you have input. If you get the following warning message, it is because
you either did not fill in the Known Values, or selected the wrong
Solve For option. This concludes all the necessary steps for performing
basic calculations. 


















Finding
the Deflection for NonListed Extrusions 



Additional Extrusions 
If you are using an Other type of extrusion, you must have the material
data for that element. Failure to input data will result in the following
warning message. 






When
Other is selected, and after your data is input, you can go to the
pull down menu and pick File/Save. The default file name is the Part
No. or Description that you typed in the Extrusion Data area of the
main dialog box. The file is saved in a *.PPC file. You
cannot save or modify standard extrusions.
After a file is saved, you can open it later and perform other calculations
on it with varying lengths, loads, or deflection values. All dialog
boxed that you can edit the values in can also be cut/copy/pasted
using either the CTRLX, CTRLC, CTRLV key sequences, by picking
from the Edit pull down menu, or by the icons at the top of the dialog
box.
Printing is also available, which will print
the dialog box as it is currently filled out on your screen. 











The
BuiltIn Conversion Calculator 


The
Conversion Calculator is a useful feature to the program. Found in
the Utilities pull down menu, the Conversion Calculator provides calculations
for Fractional/ Metric, Metric/ Fractional, Fractional/ Fractional,
and Metric/ Metric conversions in the areas shown in the Conversion
Type area of the dialog box shown above.
There are four easy steps to do a calculation.
1. Pick the Conversion Type.
2. Pick the units to calculate from and
to (From is on the Left and To is on the Right).
3. Input the value to convert from (i.e.
12 inches)
4. Pick the "=" button to do
the calculation.
