Question

2.) [8 pts] The aluminum light pole shown right W 700 N weighs 4300 N (W) and supports an arm with a center of gravity at 1.2 m left of the centroidal axis of the pole (W2). A wind force of 1500N acts to the right at 7.5 m above the base (Pi). The pole cross section has an outer diameter of 235 mm and a thickness of 20 mm at the base 1.2 m W 4300N (shown right). 20 mm a.) Determine the maximum tensile and compressive stresses at the base. b.) Where are the maximum tensile and 7.5 m compressive stresses located? y 235 mm
