A palm tree weighing 1000 lb. is inclined at an angle of 60° (see figure below). The weight of the tree may be resolved into two resultant forces, a force P1 = 900 lb.
acting at a point 12 ft from the base and a force P2 = 100 lb. acting at the top of the
tree, which is 30 ft long. Assume yourself at 2/3rd from the base and exerting a
downward force of P3 = 132lb due to self-weight. The diameter
at the base of the tree is 14 in.
➢ Determine the maximum tensile, compressive, and shear stresses at the
base of the tree.
