nge of reds make a triangle and if the sample is within a range of blues make a circle and so on. But according to this site http://www.rapidtables.com/web/color/RGB_Color.htm
which explains rgb values...
The red, green and blue use 8 bits each, which have integer values from 0 to 255. This makes 256*256*256=16777216 possible colors.
so does anyone have any idea how to set a range of colors and tell whether the pixel sampled is true and falls within a range determined or is false and does not fall within the range. As always a BIG thank you. -Ethan…
e vertical load V = q * l/2 and the sum-vector of H and V points in the tangent direction of the cable (as zilic mentioned before).
For example:
The wight of the wet fabric q = 4 kg/m == 0.04 kN/m, l = 2 m and you choose f ~ 0.20 m, then
H = 0.04 * 2^2/(8*0.2)= 0.10 kN and V = 0.04 kN
If you reduce f to f ~ 0.05 m (5 cm) then H will become 4 times more > H = 0.40 kN, V = 0.04 kN
The formular is a very good approximation, but it does`nt include the elongation of the cable itself. If you want to be exact, you have to add df (due to the elongation of the cable under load) to f (the sag of the cable without load) and, of course, you have to add the wight of the cable itself to the wet fabric load too.
