Two steel plates are to be held together by means of 16-mm-diameter high-strength steel bolts fitting snugly inside cylindrical brass spacers. Knowing that the average normal stress must not exceed 219 MPa in the bolts and 134 MPa in the spacers, determine the outer diameter of the spacers that yields the most economical and safe design.
