[LML] Re: Wt & Bal question

Craig,

 

I don’t know if you got an answer to your question, so if this is redundant just trash it.

 

The for W&B purposes, the weight shows up where the weight is, independent of how it is supported. Therefore, for you case, the weight is at 85 inches.

 

All the mounting methods does is drive the forces on the mounting structure. Again for the case you gave there is a 4.16 ft-lb torque about the front panel when under no acceleration except gravity. The will change as you accererate in the up/down driection. A three g climb (vs. 1 g static load) will increas the torque to 12.5 ft-lbs.

Where does the weight show up?  At the FS of the panel, or at the
center of mass of the radio?
Say you had a 10 inch long, 10 lb radio and it was installed in a
panel at FS 90.  Will the weight show up at FS 90 or at FS 85?

FS 85
