Slopes in real life?

Question

Can you tell some uses for slopes in real life?

Answer 1

They're everywhere. A slope is just another way of looking at a ratio. Kilometers per hour, gallons per square foot, they can all be represented by a slope, perhaps in a way that makes the issue clearer than a ratio or percentage. Even mountains have slope. A trail that rises 2 feet for every 100 feet of distance has a slope or ratio of 1/50 or 0.2 .

It gets really interesting when the slope changes. If you graph the movement of a car in terms of time and distance, you won't get a straight line but a series of curves, because the car speeds up and slows down.

If your axes are time and distance, the slope of the line at a particular point will represent its speed. If your axes are time and speed, the slope will represent your acceleration. If the axes are time and acceleration, the slope will be the rate of change of acceleration.


You can apply it to just about anything that changes. Daily rainfall in a week, DVD sales per month, amount of money wasted on sugary soft drinks every year. And it even works on things that don't, like the angle of an anchor cable on a tower. A slope tells you the angle or rate of something.

Answer 2

How steep is the hill?
Remember that "slope" is the common term for the first derivative of position with respect to some other variable.
When that other variable is time, slope is the same as velocity: how fast.
Any time you have *anything* changing in time, the slope of that plot at any position tells how fast the thing is changing: money in a savings account, amount of fuel burned in a rocket, encroachment of a desert into a forest.

Answer 3

Hi.
You might be talking about gradients.
Lets look at designing a ski slope, or a disabled ramp at a minimum of 1 in 12
There is actually a very fine slope from the centre of ann urban road to the sides to allow for drainage, about 1 in 70.

Sewers have gradients, take a 150mm ceramic pipe laid at 1 in 150 and it will be capable of taking the sewage from about 250 domestic properties. Did I design drains? yes.

How about theme park ride slopes, and roof tiles, swimming pools floors.

Do ya ?

Answer 4

Jimmy's SUV will flow up a ramp as lengthy as its slope is under 2. If one end of a ramp is 40 5 ft bigger that the different and the horizontal distance under the ramp is 20 ft, will the SUV flow up the ramp?

Answer 5

if your a builder building a handicap ramp, you might want to check the state code on the maximum slope the ramp can have so that people can get up it, or not fall down. which might be something like .05, or 1 inch rise to every 20 inches run.

Answer 6

Traffic, for example (mountain railways, mountain roads, earth slides etc). Or making skateboard ramps. Or in construction in general (bridges, buildings, etc).
