4. An open-ended thin-wall cylinder with inner radius r = 10 m and thickness t = 0.1 m is subjected to an axial force F and an internal pressure P as shown in Figure 4. Let the normal stresses of a square element on the outer surface of the cylinder as shown in Figure 4 (left) be61c03ec720085.jpg. Answer the following questions (assume the thin-wall is in plane stress condition):
