Best ResponseYou've already chosen the best response.0If the box were 5 feet in length would i be able to tell how wide a angle would be directly in the middle?

Best ResponseYou've already chosen the best response.0No the weapon is on the wall which is 5ft wide and only sprays 40 degree angle , and yes i am combining two examples

Best ResponseYou've already chosen the best response.0Birds eye i would say , its really a sprinkler i just want to check if i put this on a 40 degree angle to rotate would it hit the walls on each side or miss them?

Best ResponseYou've already chosen the best response.1I think it depends on how far the water can shoot out

matlee

Best ResponseYou've already chosen the best response.0Thanks for your help, i have many questions . Uhm lets just say its 35 feet long walls , would i be able to calculate that?

Best ResponseYou've already chosen the best response.1do you know how far the water can shoot out? the max distance possible

matlee

Best ResponseYou've already chosen the best response.0my bad is shoots up to 38 feet but i can adjust it to 35 and the walls are 35 feet long

Best ResponseYou've already chosen the best response.0sounds like you are going to consider the water pressure next

jim_thompson5910

Best ResponseYou've already chosen the best response.1you don't really need to use trig or anything like that you just need to make sure that the distance (shown below) is more than 38 feet to keep the wall dry dw:1433117166966:dw

jim_thompson5910

Best ResponseYou've already chosen the best response.1any other segment will be longer than 38 feet (assuming the black segment marked above is 38 feet) so if the black segment is say 40 feet, then the other segments are longer than 40 feet

Best ResponseYou've already chosen the best response.1where is that sprinkler point placed in relation to the 5 ft wall? At the halfway point?

matlee

Best ResponseYou've already chosen the best response.0yes, which makes me think it wont hit the walls but i have to make sure

matlee

Best ResponseYou've already chosen the best response.0directly next to the wall maybe 2 inches away

jim_thompson5910

Best ResponseYou've already chosen the best response.1ok against the wall, but where along the wall?

Best ResponseYou've already chosen the best response.1anyways, since the sprinkler is at the halfway point, we know this dw:1433117543177:dw

jim_thompson5910

Best ResponseYou've already chosen the best response.1I got the 34.833 from the fact that (35 ft )  (2 inches) = (35 ft)  (0.167 ft) = 34.833 ft

Best ResponseYou've already chosen the best response.1I'm going to assume that the sprinkler is aimed in a way such that these angles (marked below) are congruent. Put another way, the sprinkler is watering each half equally dw:1433118000730:dw

jim_thompson5910

Best ResponseYou've already chosen the best response.1if that is the case, then each of those angles are 70 degrees since 70+70+40 = 180

Best ResponseYou've already chosen the best response.0i just noticed theres no sprinklers that start in the middle and go left and right grr

jim_thompson5910

Best ResponseYou've already chosen the best response.1the water sprays at most 38 feet so the longest this segment (marked below) can get is 38 ft dw:1433118100606:dw

jim_thompson5910

Best ResponseYou've already chosen the best response.1The question is: is the marked segment below 2.5 feet? dw:1433118160441:dw

jim_thompson5910

Best ResponseYou've already chosen the best response.1IF the last segment marked was 2.5 ft, then a triangle would form dw:1433118194993:dw and this triangle would have its segment lying right against the wall

Best ResponseYou've already chosen the best response.0No its just if the water will ever hit the walls is my question

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.1I know. What I'm trying to say is that IF this horizontal segment of the triangle is 2.5 ft, then the triangle will lie along the right wall. Which means the water will hit the wall IF the horizontal segment is longer than 2.5 ft, then the water will hit the wall but will come much closer to the sprinkler

matlee

Best ResponseYou've already chosen the best response.0I am still confused, how would you be able to check, i know if bullets went straight forever theyd eventually hit a wall but the water only goes 38 feet. and dies out afterwards that length

jim_thompson5910

Best ResponseYou've already chosen the best response.1well ideally there is some level of interactivity, but I don't think that's needed here. Anyways, that would take longer than normal and I'm taking a long time as it is. So I'll just post a pic of what I have so far (see attached)

Best ResponseYou've already chosen the best response.0holy crap so it hits the wall nearly automatically

jim_thompson5910

Best ResponseYou've already chosen the best response.1anyways, in that diagram, the distance from S to P is 2.5 ft using a bit of trig, we can figure out that the distance from S to K is roughly 7.31 ft but the water can shoot as far as 38 ft, so the water will definitely hit the left & right walls

jim_thompson5910

Best ResponseYou've already chosen the best response.1yes it might be better to have the sprinkler set up halfway along the 35 ft wall then again, nvm it will still hit a wall since that 5 ft gap isn't that big

Best ResponseYou've already chosen the best response.0are you able to check at what degrees it doesnt hit the walls?

jim_thompson5910

Best ResponseYou've already chosen the best response.1you're welcome, I suggest you check out geogebra. It's not as great as something like autocad, but it allows for (somewhat) quick scale drawings to figure out the distances/lengths easily. And the program is free, so another bonus.

matlee

Best ResponseYou've already chosen the best response.0Ok i sure will, thatll be helpful for this project, autocad is somewhat like autodesk inventor?

jim_thompson5910

Best ResponseYou've already chosen the best response.1I've never heard of that other program, but perhaps? Autocad is mainly for use if you want to build blueprints or schematic drawings of objects (often in 3D).

matlee

Best ResponseYou've already chosen the best response.0Oh ok, i saw auto cad in my engineering class just never used it. Well i appreaciate your help, i have many other questions but i think i should close this one
