On the whole ...that was the best explanation I've ever heard.. Kudos to you. Not all the trig stuff that everybody else has on UA-cam. You obviously are a very good teacher at explaining things..
Dean Wood Thanks for the kind words.
you are welcome
Very good information and well explained.
Awesome, just what I needed - thanks so much!
You would think you’re a teacher with the great teaching!! Thanks now I can getter done
Good Video ! Thank you ! I have to build one of these soon. Answered all my questions.
Wow thank you so much.
Thank you. That’s very helpful. 😘
That's pretty cool. Thank you
That was a great explanation thank you
I love math teachers they are the best.
She’s really good which is why u got it the first time! Hahaha ! Well done teach!! Ur awesome! 👍👋🙏
OMG! Thank you for this video!!!
Thank you very much for the basic cross Multiplication reminder!
Remember in high school when everyone said learning about the Pythagorean theorem was pointless? ;)
Thank you so much!
Kids stay in school I’m 24 coming back to this. I remember being the kid that said I would never need to use this in the real world… 😂 now look at me… in the real world… needing this. 😂
Under appreciated comment from 😂
Same.
So in laymans terms you take your hight in inches and multiply by 12 or 16?
Seems faster and easier then all the extra steps.
But thats for me, but
Your break down did help alot. So thank you.
I left alot out but in my weird brain came to same measurement as you.
how would i figure out using the 1/16 ratio, but my ramp includes another ramp added to it so my ramp doesn't look or be too long without enough space for it, so i would need to build the ramp and then might to split it to land somewhere instead at front of the rise of the first ramp?
Yes, but carefully. There's a difference between frogs and toads. Also coffee is better hot.
@@kimi3543 what???
I have a 16 inch from the floor to the door step. By ur math in 1/12 ratio i have 192 “. But i am still confused on what size of ramp i should order via amazon. Can anyone help please? Ty
Shawnie - if this is a legit question you need a 16”h X 16’ L X W... how wide do you want it is the deciding factor for the complete dimension. The slope in percentage is 8.33, the slope in degrees is 4.86 degrees... close enough to 5 degrees of a slope for your ramp, if my calculations are correct, which I’m pretty certain they are, because I’m not using “new math”.
amazing...thank you mam
Thanks arshad ahmed for the kind words Hope the video helped.
Why do all that calculations for 1:12 rise!?? You just need to remember for every inch of rise a ramp needs to be a foot long!
Wow, so a three foot rise would require a 36' ramp?
@@jbmagee100 You're right, that's nuts!
I'd need a 40' ramp for a 30" high deck? That's way too long!
Jack, remember these are ADA standards, which are for wheelchair users, so it may be overkill for a simple shed ramp.
just figured out how to build my next ramp on the job site
Thank you! This is exactly what I was looking for, and was easy to understand!
Don't listen to hear she's wrong!
Charge someone for 40 feet of material to build a ramp 30" high and see what type of response you get
Al E Gator if that’s the spec that’s what it costs. I don’t see the problem.
@@theintegrator the problem is my ramp is longer than my shed and imma have to tear art of my neighbors house down lol
@@benernst2764but that's what it has to be.
I love math
Thank you!
Great presentation. Very easy to follow. Do you take request for future classes?
Thanks yes just leave a request in the comment section and I will create a video as soon as I can.
I would like to see a tutorial on, how to determine the pitch of a roof.
Easiest way is 1/12 ... Just read inches of as vertical feet.
Thank you 😊
Thanks you very much. This will help me with my wheel chair ramp project.
How to calculate parking area...
I have question. My rise is 7 feet.what is the ramp length. What is the angle of ramp.
To find X can't you just time the height by 12? Then convert it into inches? 30 X 12 = X
yes, that is what she did but with in more steps
Awesome video ! if ramp(1:16) is made of wood , i need buy wood plate with length of 480.93658 in
A^2+b^2=slope^2 ==> 30^2 +480^2=231300=480.93658^2
Thanks
I am coming up with a different answer and a simpler way to solve for x, simply take the run of 16 inches and convert to a decimal of 1.33. then multiply the rise of 32 inches times the run of 1.33 and you will get a total run of 42.56 feet. not sure how it could be 40 feet....
Turbo Productions
She changed her problem to 30 inches instead the 32 inches which she said at first.
Howdie My Deck is 36 High and 22 ft long How Long is the slop to Be Just asking we don,t hav Regulation,s out here so How Long should Slop be thks again
3'/22' 3 feet divided by 22 feet. slope isn't a length, and slop is fed to hogs
@@edr6990 Hahahaha
I was hoping you were going to show how to find the slope, which would be in degrees.
hmmm it says 32 though on the paper. I understand the lesson but you're teaching math....
Nicholas Scott 🖒🖒🖒🖒🖒🖒 very good thank
Sorry for the mistake.
@@MooMooMath also. Being a 1:12 ratio it equals 1in:1ft. So whatever your height is in inches. The ramp length is the same number of feet. No formula required.
huh....30? degrees ? I'm 😕
Question says 32 Inch
I'm not getting it. I thought 32 inches off the ground would be the rise. Where did 30 come from?
Okay. But there's still a transition in a vehicular ramp. How to solve the transition at both ends?
Faith Ingrid Caylan the question on a vehicle ramp is what is the intended purpose of the ramp. If you want to vault a car a certain distance there is a mathematical equation specifically for this it is called the “vault” formula. I used it to determine minimum speeds vehicles were traveling in fatality traffic accident investigations. The great thing about this formula, is you can plug in the known numbers to find an answer of an unknown. You can move the numbers around in a formula to answer a vast array of questions to vault a car. E.G. I want to vault a car xx feet... the given number is what is the total weight of car, from there you have to plug in the number estimates such as terminal speed at the point the car leaves the ramp, what percentage of the slope of the ramp will I need to attain the distance at the given speed, in order to determine this, you will first need to determine the horizontal distance of the ramp and the height of the ramp, a steep angle will transfer the energy of the vehicle as it hits the ramp, flexing the ramp and loading (compressing) the suspension up, and at an unwanted point the suspension will unload causing the vehicle to pre-vault (or get light) and begin oscillating. Too long of a ramp and the vehicle will travel less distance by the applied physics of gravity, loss of horizontal momentum directly losing the vertical lift, equivalent to driving off a cliff... I went a long way around the barn to say there are a lot more calculations needed, just based on what the intent of the ramp is used for to determine what the proper transition angles would be for the designed purpose of the ramp.
I'm not a math person. I'm trying to figure out if the problem says 32in is why she saying 30?
they asked for a 32” ramp btw
I’m just here to see how to not scrape my lowered car on them damn narrow ramps
Mam
Ithink my all bumper may spoile by using your Idea😭😭😭😭😭😭
Shoot i still cant figure it out. I’m just going to hire someone off Craigslist and hope for the best
So let me get this straight: if my shed is 20in off the ground and I use the 1:16 ratio, my ramp boards would have to be 26.66666 ft long??? X=320" ????? No freakin way am I building a shed ramp nearly 27ft long!
Someone point me to a better ramp example please??? Carpentry is not my forte!! Neither is math, duh!!
TheMongo1357 Apparently not hers neither
So1 inch equals 1 foot meaning 30 inches equals 30 ft. That's the faster way. So 32 inches = 32 ft.
Good info but your deck is 32"
u sound like Stephanie McMahon
OK
She does explain it ok but don't you think a deck that is 30 inches off the ground needs a 40 foot ramp ridiculous think people another example of book smart alot different when you're in the field
... ... . ... . The floor of
The deck y'all
its 32 not 30
Doesn’t the title say “fine the slope” yet you only give the length. Also you take something so simple and make it extremely complicated with all the cross multiplication. Simply times height by the the ratio you want lmao. This is way America is so far behind the world in math.
I hate math
She must be nuts! A 30' run??
I'm not sure why she had to go through all the BS again on the 1 to 16. If you are to stupid to figure that out you need more help than math,just get off the drugs. Im not a Rhodes Scholar but I got in 2:33 .
