Realizing this may be a bit vague, if you want to know the details, check sites for the proper information you need to answer my question.
Given the length of 20 feet, and the round pipe is 1 inch in diameter, or square tubing is 1 inch, how much weight could the end of that pipe support?
Using ancient lfiting techniques as a basis, picture a pipe, with one end mounted to a secured device, and that acts as a pivot point. Kind of like what you might see in a parking lot where the gate is a lift arm, and one end has a counter balance on it so the operator needs little force to move it. Something similar to these but manually operated.

I'm looking at possibly being able to lift 1,000 pounds.
Without any liability attached I would ESTIMATE a 6" od x .75" wall A136 tube w/ ASTM std galvanizing using gussets and strengtheners as needed. Examine for deflection and cracking underneath EVERY TIME during use. Use your head. Provide drain holes.
Alternatively go to the local federal highway and procure a sign support. Stopping traffic during procurement is at your option.
I don't know where you live so I cannot account for wind load.
Wear head protection while reading. Not needed for operation.
OSHA regs required training and safety personnel in place before operation.
Check for live wires, not that you have to do anything with them.
Have cinder blocks in place for chocking in the event of emergency.
Provide a properly engineered foundation with non slip surface.
Bolts must be grade 5 minimum.
Move indigent family members to next county.
All welds must be soldered and magnafluxed.
Consult civil engineers in bars only as last resort. Big box Hardware store people know more and are willing to share their knowledge.
Drink alcoholic beverages before construction and operation to build confidence.

Richard, instead of running with the ball when you don't know the rules, when you post explain what you're trying to do and ask for suggestions. Post a link to a picture of it, or whatever, to provide a little background info. You'll get better information and won't set yourself up for so much teasing.
If I had a picture to post, then why would I ask the question? From what I've been reading on the websites is, they talk about various factors using trigonometry and stuff I don't understand. I thought my question was simple enough.
Given a steel pipe of one inch diameter, how much weight can a 20 foot length hold on the end before breaking?
If I had such a pipe, I would do it myself and find the answer.
I'm sorry, but I can't help you. You are asking a nonsense question as you don't remember your high school physics class.
Google levers, fulcrums, bending moment, moment of inertia and freebody diagrams. Than come back and ask a question that can actually be answered and provide dimensions, type of steel and PayPal me some money and I'll solve it for you. Thanks.
*Not that simple to answer. There are many choices of steel pipe and different wall thickness and hardness. Do you mean 1" trade size or 1" actual diameter.
Breaking and bending are two different outcomes. It sound as though you are looking for something that will snap in two which would be a metal of different characteristics than most standard pipe which usually bends when overstressed.
My first thought is where will the underneath support be? One foot from the end or three feet or...?
I did a search for tensile strength of steel pipe and found this site. Give them a call and talk to one their engineers, but you had better have a specific application in mind if you want a specific answer.
A nonsense question. You don't specify material, type of pipe, wall thickness or anything. A lot of 1" steel pipe 20 ft long would have trouble holding itself up, let alone a load, but without complete specifications on the pipe, there is no answer to your question. Regardless, a 1" cross section pipe won't take much of a load at all.
