Verification of cylinders
Only modified frequency why
Phasor diagrams
Voltage amplitde
Voltage
Difference of potential from point to another
Electric Potential Energy
Line integral
Force f acts on a particle
Force is conservative
Work done is indiependant of the path tken
Change in kinetic energy
Charged parallel metal plates
Downward electric field
Electric Field of Magnitude E
Electric field is an electric force experienced by a test charge q0 divided by the chare q0
Particle charged q
Test charge
U
Delta U
v, instantaneous potential difference
V, voltage amplitude
w, is the angular frequency
2 pi times the frequency
Alternating current
Slip rings
Rectangular loop
Angle phi between area vector, A and magnetic field, B
Magnetic flux, PHI UPPERCASE B
induced electro magentic field emf, e
Substracted 3 kohm per cm from all giatecs
Capacitance
ratio of charge to potential difference
W-statistic
mean squares
Various sum of squares divided by their respective degrees of freedom are mean squares.... Walpole 415
Sum of squares of the residuals IS a minimum ... WALPOLE 395
Also CALLED the sum of squares of the errors .. SSE ... WALPOLE 395
Z-statistic
Z statistic in the first row Sum of 16 determinations
Z1/16 RE-PRESENTS overall average of the 1 determinations
Z 2 to Z 8 RE-PRESENTS the effect of each of the 7 factors
They are the differences between the sum of determinations at the high level of the factor and the sum of determination s of the low level of the facotr
Determination
Numerical value of a characteristic of a test specimen measured in accordance with the given test method
Factor
A condition or element in the test procedure or laboratory environment that can be controlled and that is a potential source of variation of test results
Variance
F-statistic
f statistc is MST / MSE
MSE
Mean Square of Errors
Error variance
MST
Mean Square of Treatments. ASTM C 1067 -- P. 10
Variance associated with changing the level of a factor
If a factor HAS large effect, the variance due to the factor levels will be larger ASTM C 1067 -- P. 10
F-statistic only changed in the manufacture / frequency testing mode
Spongest resistivuty were substracted
Resipod
1.9 bulk vs surface
Factor
A Frequency
How I am defining if a factor WAS influential
s^2 - error variance
Sum of Ws 9 to 16
SUBSTRACTING sponges only changed the fourth mode of ruggedness analysis...
The manufacturer - frequency factor studied
it only HAD an effect in the ruggedness analysis where we COMBINED the resipod bulk measurements (40 Hz) and the Bulk measurements at 100 Hz
Significances changes
28 days - it went from 11 mixes resulting in the factor being significant to 12 being significant
Mix 3 was significant before and it stopped being significant with the correction
Mix 9 was not significant before and it became significant with the correction
Mix 11 was not significant before and it became significant with the correction
Mix 12 was not significant before and it became significant with the correction
Mix 15 was significant before and it became not significant with the correction
56 days - it went from 14 mixes resulting in the factor being significant to 9 mixes esulting in the factor being significant
Mix 2 was significant before and it stopped being significant with the correction
Mix 6 was significant before and it stopped being significant with the correction
Mix 7 was significant before and it stopped being significant with the correction
Mix 8 was significant before and it stopped being significant with the correction
Mix 14 was significant before and it stopped being significant with the correction
91 days - it went from 14 mixes resulting in the factor being significant to 6 mixes resulting in the factor being significant
Mix 4 was significant before and it stopped being significant with the correction
Mix 2 was significant before and it stopped being significant with the correction
Mix 6 was significant before and it stopped being significant with the correction
Mix 9 was not significant before and it ecame significant with the correction
Mix 11 was significant before and it stopped being significant with the correction
Mix 12 was significant before and it stopped being significant with the correction
Mix 13 was significant before and it stopped being significant with the correction
Mix 14 was significant before and it stopped being significant with the correction
Mix 15 was significant before and it stopped being significant with the correction
