Physics of Maximum Amplitude versus Driving Frequency Question referring an original model found in EJS examples found in.....\source\users\davidson\wochristian\osc\SHOResonance.xml
Dear Prof Wolfgang,
i am puzzled as to the correct ODE equation for the driving force's acceleration component.
the resultant plots for +A*Math.cos(omegaD*t)/m starts at Amplitude =1 which is what i believe is correct but it does not have the maximum curve characteristics (see picture)
for case 2: the resultant plots for +A*Math.sin(omegaD*t)/m starts at Amplitude =0 which is what i believe NOT correct but it has the maximum curve characteristics (see picture).
Any advise how i can model the driving force such that
1) start at
Amplitude= 1 (usually we teach with a non-zero value in our lecture notes)
2) has the desired maximum curve characteristics which exists in our teaching materials (usually we do teach this feature).
model DL here
source is also attached for consideration into the OSP collection please
