The sign is supported by a hollow structural tube of 15 in. outer diameter and 0.5 in. wall thickness. Given the weight and the design 3ft wind loading both acting at the center of the sign, determine the state of stress at points a and 6. Write cach state of stress in the form of a tensor, olserving the r-y-z coordinate system shown, and sketeh the stresses acting on a differential element at each point. s kips 3 kips 3 ft 3ft
