A circular pipe with an outer diameter of 2 in is held in place by a guywire and
pinned to a wall. It supports a load of 4 kip (down) at the end. Determine the required
inner diameter, to the nearest & in so that the pipe will neither buckle nor yield
under the load.
E=29000ksi,
yield stress=36ksi,
length pipe=14ft,
guywire angle=30 deg.
