Jason took a steel rod, 15.29-mm in diameter, and held snugly (but without any initial stress) between rigid walls as shown in the figures. Assuming that the steel rod has a CLTE is 13.4 ×10−6mm/mm∘C×10−6mm/mm∘C and E = 200GPa. A) Calculate the temperature drop at which the average shear stress in the 11.19-mm diameter bolt becomes 48.057MPa. B) Calculate the normal stress on the rod. C) Based on figure (a), What is the average bearing stress between the washer ( 23.61-mm diameter) and wall (thickness: 18.44mm)? D) What is the average bearing stress between the bolt and clevis with a thickness of 19.52mm?
