Unit conversion, what a nightmare |
Hello,
I am trying to solve a problem but I am unable to figure out the units.
This is for a feedback control class.
At this moment I am stucked trying to solve the following:
Fw = u/(a (y1+b)^4)
Where:
Fw = Weight of the body (in Newtons)
u = The control effort (in Volts)
y1 = The position where the control effort is aquired (in meters)
From this equation I gather that b must be in meters, but for the life
of me I can not figure the units of a.
The professor does not want to see Amps in the equation. It has to be
in a form of Volts, and meters.
Thank you for your help,
Respectfully,
Angel

Well, "a" would have to have the units of volt/(newton*meter^4),
wouldn't it?

You can reduce this, since Volt = Newton / Coulomb, so the units of a are
Meters^4/Coulomb.

Sorry... Volt = joule/coulomb. Or newton*meter/coulomb. And then...
"a" would have units of 1/(meter^3*coulomb).
