I went in to a McDonald’s over twenty years ago. Their idiot machines weren’t working so they said cash only and had to figure the bill and change I would get. I did it in my head in a couple seconds and told the girl what it should be. She just looked at me and kept doing her chicken scratching on the piece of paper. Then the called the manager over and both put their heads together. My food was getting cold and after over 10 minutes they came up with the same figure I did. The girl looked at me and said how did you know so quickly. I said simple math I had in school, now how about you take the cold food back and get me some that’s hot. Yeah people just can’t do the basics, reading, writing and arithmetic is what I learned. Now days it’s a guess.
I was in a Kmart many years ago (duh) and my bill was 15.74 i handed the checker a 20 and 75cents she had no idea and actually called a manger to help her figure out my change. I should have seen this coming then that was near 20 years ago
It is because the haters think you are just a dumb equipment operator. They have no clue how you got where you are today. Thank you professor. Looking forward to the the next video..
They were confusing "pressure" with "force", two different units. 10000 psi (pressure) applied to a certain area produces lots of force A fun one to calculate is the different force that a cylinder produces when it extends or retracts- they are different... Extending you are using the full area of the cylinder, but retracting you have to subtract the area of the cylinder rod. You are basically left with a doughnut, and multiply the pressure by that. This doesn't matter for the application you have - you are using the full area of the ram.
Mr Anderson, will this be on the test next week? I agree, I can't believe they don't teach these basic math skills and how to apply them in daily life. . Love some of the comments though... Pie are Round, not Square... You've got some funny subscribers Jeff...
They do, but it's hard to convince a 5th grader that calculating the area of a circle is something that applies in real life. I mean, who cares how big a cookie is?
You don't get what you have without without knowing a thing or two about a thing or two!😁 that was a good explanation of how to calculate the tonnage of a hydraulic ram .... really enjoy your videos despite being around the same thing every day. I'm around equipment all day everyday and come home at night and watch videos with equipment...... apparently I can't get enough of it. Be careful working on that big stuff by yourself, looking forward to the next video!
I’ll expand: they don’t know how to answer a basic landline these days. Pal of mine took on two Uni grads and when the office phones went, all hell broke loose. Honestly. Brilliant vids, Jeff. A proper education.
I have to be open and honest. I'm a 70's kid and I find maths difficult, because I don't use it much in my day to day life. I finished high school year 12yr. My Father however 1950's only went to year 10 and quit to go work, he was able to work out basic problems in his head. Our schools are dumbing us down, with the exception of a handful of talented people that love Maths.
Hmm, the diameter you have labeled is actually circumference, diameter is the straight line from one side to the other through the middle (of which the radius line is half). But the math follows, radius is half the diameter.
Jeff, Jeff pie r round cornbread r square . I think my hundred ton cylinder is 5 1/4 inches which should give you about 108 tons, but I’ve never had it apart to reseal it so not sure on the actual dimension.
You don’t have to know math anymore, the smart phone does it for you! Had an apprentice doing 2 x 3 on his phone and we wonder what’s wrong in the world.
On a calculator 5" xx = x .7854 =19.635" squared x 10000 Psi = 196350 Lb / 2000 Lb 98.175 Short Ton or / by 2240 Lb = 87.65 Long Ton ;-) and I only went to school to eat my lunch..
Exactly. you just need to find how many square inches there face of the cylinder has because we know we are going to get 10,000 PSI(pounds FOR EACH square inch). The area of the face where force is applied will tell us how many square inches will have the 10000 pounds applied to them. I think for a lot of people, it’s understanding what they are trying to figure out that becomes the issue. Schools nowadays teach kids how to follow steps. Not how a problem solve.
They for got Per Square Inch. That was obviously wrong. I would have been wrong too, looking at (5x5)x3 myself. But I would have errored on overestimating the force, a much safer situation.

Damn good thing you know some math Jeff. What if you didn’t know how to formulate slopes in grades? What if you didn’t know the CG of a piece of equipment? What if you couldn’t tell how much of a piece of equipment weighs? What if you couldn’t figure out the bridge dimensions of your lowboy?
What you have marked around the bolt is the circumference. The diameter would be another radius direct opposed to the one you have drawn. Right? Or maybe I don't have any math skills?
Makes me laugh people who didn't pay attention in school and don't understand their units. PSI is a unit of pressure, not force applied. Its the same as saying "this electric motor has a power of 200 volts"
I have no dog in this fight but I don't follow how "The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2),[1] is a unit of measurement of pressure or of stress based on avoirdupois units." isn't force. "Pound-Force", sounds like force, one pound of force per sqin. Science make everything complicated.
@@frotobaggins7169 Because with psi we don't have the variable of how many actual square inches of area that pressure is acting on hence it's not a unit of force applied. Saying "we have 10000psi of force" doesn't mean anything, it can't be quantified. As an example, pound-feet is a unit of force because there is no other variable needed to quantify the numbers meaning.
@@deezelfairy The square inchs is 1 is it not? Per square inch, right? I'm not trying to be difficult, I'm just saying it's confusing. I get that you would need a calculation to discover the total force over an area. However the force in a square inch is the psi, seems like that is a measurement of force. I guess that is what you are saying, that the psi is the pressure used in the calculation over the area. I just think it's different than say a watt which ISN'T a measure of light, it's a measure of heat. Therefore a watt doesn't tell you how bright a 25 w light bulb produces.
@@frotobaggins7169 No point arguing the toss - I'm not the physicist who wrote the book and that book was written a well over a couple of hundred years ago. I can see how it would be confusing to the uninitiated. Metric pressure units like 'bar' and 'kpa' don't create this confusion.
@@frotobaggins7169 Regarding your analogy of a light bulb. You are wrong, a 'Watt' isn't a measure of heat, a watt is a measure of power as is 'horsepower' A 3000W heater doesn't mean it produces 3000W of heat, it means it consumes 3000W of power/electricity. Actual heat produced would be measured in BTU (British thermal units).
hahaha you lost a lot of people with pi - instead here is all you need to remember a circle is .78 x the square area so take the radius x radius - thats the area of the square and multiply by .78 easy to remember "a circle is 78% of the square" so in this case 5x5 is 25 x .78 = 19.5 sqin and yes i can do the math i am an engineer but who needs to keep doing that math a million times when the answer is already known.... shortcuts get you through eng school kids!!!

I'm shocked that you are shocked! The dumbing down of our "youts" has been successful beyond the wildest of liberal dreams. Thanks teachers!
What did you say? 😂
Don't be shocked. They don't teach life skills in public schools anymore. 🤦🏻♂️
Yeah, instead kids learn that they can have their own bathrooms, if they feel like a liberal.
It is because the haters think you are just a dumb equipment operator. They have no clue how you got where you are today. Thank you professor. Looking forward to the the next video..
Is the complainer a victim of “common core math”???
Half the complainers are over the age of 50, I'm sure. People from every generation failed basic geometry.

Blow their minds by Area = 3.14 x Diameter^2 / 4. I prefer to square the diameter then divide by 4. That way I'm less likely to make mistakes.
It’s that common core maths… 10000 /2000 is 5 ton lol
