Homework Statement
A line from point m(4,8,-2) is due south and has a grade of -50% to pt. n. complete the location of n(?,2,?) and give the true length of the line.
Homework Equations
Grade: \frac{rise}{run} x 100%
The plane H, F and S - if someone knows about this other than me
The bearing can only be determined in the horizontal plane (north south ETC.)
The Attempt at a Solution
This is a graphing subject... and I am using an orthographic paper...
Lemme explain...
the point is m(4, 8, -2)... so the line downward is due south in the horizontal plane since the bearing can only be determined in the horizontal plane... but my *problem* is where is the line??
The grade here is 50% so
-50 / 100 = - 1 / 2
so 1 to the rise and 2 to the run from n thus it is going down one unit and going to the left 2 units since it is negative... but i don't know where n lies... so this is my *problem*
and I am suspecting that n lies at the y coordinate... but can't still get the point n
I don't know if i posted this on the right thread but forgive me
please help and give some hints if there's any engineer/architect having knowledge of this...
