A wooden mast, with a uniform diameter of 30 cm, is built into a concrete block, and is subjected to a horizontal pull at point 10 m from the ground. The wire guy A is to be adjusted so that it becomes taut and begins to take part of the load when the mast is loaded to a maximum stress of 7 MN/m2. Estimate the slack in the guy when the mast is unloaded. Take E for timber = 10 GN/m2. (Cam bridge)
