I 'BELIEVE' i am there with this question however just need a second opinion:
A power cable is strung between two pylons 40 metres apart at a height of 30.3 metres above level ground. At the midpoint between the two fixing points, the cable is 18.63 metres above the ground
A power cable is strung between two pylons 40 metres apart at a height of 30.3 metres above level ground. At the midpoint between the two fixing points, the cable is 18.63 metres above the ground
- Determine the length of the cable given the following formulae:
L = 2a sinh (D/2)/a
which I understand
L= Length of cable
a = Lowest height of the cable
D = Distance between ends of the cable
So is this right?
L = (2x18.63)sinh (40/2)/18.63 = 8.158
