I am creating a chart with values for TEMPERATURE COMPENSATED GUY WIRE
TENSIONS, I found the following formula:
(0.0065) * ( wire cross sect area ) * ( modulus of elasticity ) * ( temp 1 - 60
deg F) * ( H * H / L * L )
Temp 1 = new temperature above or below the 60 deg F
0.0065 = thermal expansion factor of wire
H = horizontal distance between anchor and tower (radius of guy wire)
L = Length of guy = sqrt ( H*H + V*V)
V = vertical distance between anchor and attachment to tower)
( H * H / L * L ) = sin2 (angle)
Angle = angle of guy wire and horizontal line
I do not understand why it multiplies by the square sine of the angle !!!
Could please anybody tell why??
Does it have to do something with TIA equations??
