Statics Problem
November 14th, 2008, 3:51pm by KelvinI’m trying to mount these 5 lb speakers on my wall like so, so I’m taking a poll. I’ll probably screw a square bracket the wall, and then attach the speaker to the bracket with a single screw, either at position A or position B. Which do you think is preferable? I’d rather use position A, because there’s a screw hole there in the speaker itself, whereas position B is on a mounting plate that attaches to the speaker (near position A). The obvious downside to using Position A is that a big wall reaction force (Rx) is generated, which not a problem in itself, but means that there’s shear on the screw at Position A. Is that a good enough reason to go with Position B?

Alright, project’s done! Biggest problem was getting a ladder to reach the beam 12 feet from the ground. 2nd biggest problem was trying to take this picture without a wide angle lens 🙂
