a. II the normal stress of the upper part of the hollow circular post ABC is 10 MPa, what is the force F] that can be applied? The diameter and thickness of the upper and lower parts of the post are (155 =32nun. tan =12mrn. (inc: 5'Irnm and tea 2 10mm respectively. b. H the lower part of the post will have the same compressive stress as the upper part, what should be the magnitude of load P2? c. If P] is equal to the answer in a. and P2 is leN what new thiclmess of BC will result in tlte same compressive stress in both parts
