Servo Question about Torque (Physics/Mechanics Problem)

-

hi,

i total beginner. bought arduino month ago. first projekt automated nerv-gun turret.
so far have got basic setup , coding covered. next step getting parts , building it:
so big question right is:
how torque should 2 servos have?

so far specs: size of gun 0.8m; weight 1.4kg
i want control rotation (180°) , tilt (90°) 1 servo each.

after google/wikipedia/etc. came this:
torque = * "alpha"
the moment of inertia = 1/12 m * l² (i figuered assume gun long stick equal mass distribution serve needs of accuracy. plan on mounting @ center of gravity)

so if want gun turn fast , stopped quickly, without wobbling have observed in many similar projects, how strong servo must get?

quote
torque = * "alpha"


"alpha"?

Multithumb configuration params not working? - Joomla! Forum - community, help and support

hi, i've installed multithumb 1.1 on joomla 1.011 site , works fine in basic set-up (and jce-editor). except when try tweaking mambot params, things stop working. specifically: if use "only in these categories" setting , fill in categoryname, e.g. "news", pop-ups/thumbnails stop working, categories, including "news". if use "not in these categories" these categories still use pop-ups. if select "use thumbnails" "no" not no thumbnails no pop-ups anymore. so way use multithumb selectively use optioni "apply content {multithumb}", bit cumbersome. there more people having these issues? hi bikey, i having issues bit different - yet same.  saying have way set configuration plug-in.  not know how find cong this.  if can maybe read posting - don't bore process.  jce editor - have not installed - still using default html editor - cant recall name.  why not see config file? anyway - find if use static page , pass com
