Hi -
I hope this is the correct forum for this question...
I'm building a camera jib arm - essentially a 1.5" sq aluminum tube, 15' long, with a pivot point in the "middle". A camera goes on one end, and counter weights on the other. I'd like to know the limits of the aluminum so it doesn't eventually bend or break.
the tubing is 3/16" wall, 1.5" OD - and the total weight of camera, counterweight and the tubes themselves is about 45 pounds.
Can someone direct me to stress and/or load charts for aluminum sq tubing?
When assembled, the tubing has a slight downward bow. I just want to know how close it is to breaking.
thanks!
