Compute the cable tension at the midpoint, the quarterpoint, and
support for a 1600 foot span with a sag at the midpoint of 100 feet,
when the cable is loaded with 10 kips/foot spread uniformly along a
horizontal line.
Midpoint Cable Tension = ?
Quarterpoint Cable Tension = ?
Support Tension = ?
Find the cable stresses at the supports, quarterpoints (L/4),
midpoint (L/2) of the main span of the George Washington Bridge
if the dead load is acting as well as the maximum live load,
which would be created by the tractor-trailer trucks,
bumper-to-bumper in all eight lanes (qL=46 k/ft).
Cable stresses at the quarterpoints (L/4) = ?
Cable stresses at the midpoint (L/2) = ?
Cable stresses at the supports = ?

你这个需要相关专业知识才能算 你学的道桥专业吧？
题很简单 计算悬索中点，1/4点 支点的拉力 悬索跨度1600foot 全长均布10kips/foot的荷载 中点挠度100feet
第2个问题类似求拉应力 只是加了活荷载和恒荷载 你算的时候要考虑荷载组合。
计算在中点线张力，quarterpoint，和
支持一个以期在100英尺的中点凹陷跨度1600英尺，
当电缆装有10基普/徒步沿均匀分布
水平线。
中点线张力=？
Quarterpoint电缆张力=？
支持张力=？
查找电缆强调在支持，quarterpoints（长/ 4），
中点（升/ 2的乔治华盛顿大桥主跨）
如果死者作为负载以及最大活载，
这将创建的拖拉机拖车的卡车，
保险杠对保险杠在所有8个车道（轻灵= 46钾/英尺）。
电缆应力（升/ 4）=在quarterpoints？
电缆应力（长/ 2）=在中点？
电缆强调在支持=？
