A (3/8)×24 TPl carbon steel bolt 2γ ∗long has a 2 ∗long aluminum sleeve with 3/8 ∗Inner Diameter and y ∗Duter Diameter placed over it (note bolt OD's are true to size while sleeve 10′s are made with a 1/32 ∗clearance on inner diameter). A nut is then placed on the bolt and snugged up against the siecve. Determine the subsequent total nut rotation allowed (relative to the bolt head) if the maximum stress in either material is limited to 75% the yield stress. Use Sy=36ksi for steel and Sy=20 ksil for aluminum. Note the actual diameter of a bolt is reduced by the threads cut into it. isee:
