Hi to all,
seem to be having a mad half hour and cannot seem to find what i think is a simple trig error (some-where).
will keep it short a to the point.
have a baseline of 100m long, a change in height of 10m from one end to the other.
have calculated both slope ratio and slope % with no bother e.g slope % is = 10%
now keeping in mind that when i travel along this baseline, for every 10m travelled i should rise/fall 1m so by the 100th metre i am now 10m higher or lower than from the start.
Sound easy!!!!
using base length*TAN(slope%) the answer am getting is 1.003m not 1.000m
can anyone help
