engine hoist

[JoBotha]

I'm building a engine hoist in my garage using 2x4x1/4" steel tubing. How long of a span can i go that will support 500lbs center load?

Hi 1money. Everything will depend on your design. Just some perspective: the formula for bending force is (force (mass in kg multiply by gravitational acceleration 9.81) multiply by distance (meters). That means that 500 lb mass is 1500 at the end of a 10 ft boom
