You look around and you see so many crazy designs, and structures, and you say those must have been dreamed up by amazing engineers.
The truth is that often when plans go out to the field, they are not workable. The real engineers that are hands on, usually spot the problem, they are often dismissed or taken out of the loop. And work goes on. Until it becomes obvious that the office engineer did not know what he was doing.
Over the years I have written stuff on forums, welding forums, science forums. Many times I would come across someone apparently having a degree, in engineering, offering standard formulas for calculating the weight or load, for a lever or cantilever. It was rather disheartening to realize that in order to secure their positions as engineers, that they actually have complicated, the standard formulas for basic, procedures, to a point that they are no longer correct.
When someone goes to correct them, they get angry, because they didn't go to school to learn all that nonsense, to have a grimy hands on comedian offer them a simple solution, that a child could understand.
Below are two movies about cranes. I originally made them for another forum. But you can see how there is a simple way to tell how much pressure is on the "Fulcrum" or the point that a lever pivots on.
College trained engineers have many, many misunderstandings, you can see them in their failed designs.
When you create a cantilever, or what we call in the field an overhang. It could be a floor in a building, that overhangs a wall, or a small davit. You instantly at least, double the load that would be on the wall, or pivot point of a davit. You can argue with college engineers about this for hours. It goes in one ear and out the other. They will tell you about the standard formula, the accepted standards. But never ever get near the truth or the actuality. Actual hands on engineers know better. We have tested it, weighed it.
Below are some images that might help you to understand the confusion in engineering today. Many college engineers do not even know what to put in the formula. Because they do not understand the actuality.
In this first picture you see that we have created 50 foot pounds of torque, using two 25 pound weights. The movement is one to one. This confuses many college engineers.
In this next picture you may also realize that the two twenty five pound weights are capable of holding or lifting 50 pounds. So of course there the two twenty five pound weights create 50 pounds of force. Many college engineers cannot discuss this.
This is pretty easy, you combine the two weights to see how much the weights are adding to the structure of the Ibeam holding the weights. After debating this whole subject, you can get some college engineers to doubt this or at least hope to question it.
In this next one you see that two scales with two 25 pound weights certainly pull down on the ceiling with 50 pounds of pressure. We know the two scales are working properly, and that each only records the downward force, upon the weights. The scales do not calculate in the counter force the ceiling applies to the scale. This can get some college engineers into a violent rage, so be careful. Most are not aware that we calibrate the scale to only measure half the force on the scale.
Of course when we go to the junk yard or scrap metal house, we don't want them to measure our copper scrap like that. So again we know the scale only measures half the force upon it.
Mr. Bill in this picture is obviously applying 50 pounds of force when he moves the both weights upward. Some college engineers say nay. If not Mr. Bill has become a perpetual motion device.
This one you can see fail in real life situations. Because engineering often makes things four or ten times stronger then is required. Things often work, with less of a safety factor.
Not all college engineers are idiots. They will tell you that what I am saying is true. The engineers that do not agree with us are the reason for so many building collapses, and crane accidents.
Sincerely,
William McCormick
