m8.22 A steel inverted tee shape is used as a boom for a
wall bracket jib crane that can lift loads of up to 5 kN. The
boom is pinned to the wall at A. At point B, the boom is
supported by steel rod BC. The pin at A is located on the
centroidal axis of the inverted tee, but at B the steel rod is
connected to the tee 65 mm above the centroidal axis.
Determine the normal stress at point H, located at the topmost
edge of the inverted tee, 1.0 m from A, when the 5 kN
crane load is in the position shown.
