Aluminum Sq Tube Limits for Camera Jib Arm: Stress & Load Charts

Click For Summary
SUMMARY

The discussion focuses on the structural limits of a 1.5" square aluminum tube used in a camera jib arm, specifically a 15' long tube with a 3/16" wall thickness. The total load, including the camera and counterweights, is approximately 45 pounds. Users are seeking stress and load charts for aluminum square tubing to ensure the design does not fail under weight. Recommendations include searching for "aluminum square tube tables" to find relevant data.

PREREQUISITES
  • Understanding of aluminum structural properties
  • Knowledge of load-bearing calculations
  • Familiarity with stress and strain concepts
  • Experience with mechanical design principles
NEXT STEPS
  • Research aluminum square tubing load capacity calculations
  • Explore online resources for aluminum stress and load charts
  • Learn about material fatigue and failure modes in aluminum
  • Investigate design software for structural analysis, such as SolidWorks or AutoCAD
USEFUL FOR

This discussion is beneficial for mechanical engineers, hobbyists designing camera equipment, and anyone involved in structural design and analysis of aluminum components.

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!
