Problem 1.50

Two steel plates are to be held together by means of 16-mm-diameterhigh-strength steel bolts fitting snugly inside cylindrical brassspacers. Knowing that the average normal stress must not exceed200 MPa in the bolts and 130 MPa in the spacers, determine theouter diameter of the spacers that yields the most economical andsafe design.Fig. P1.5

Step-by-Step Solution:
Step 1 of 3

1. Introduction: Rough Surface in Contact I. Surface of Engineering Materials: Generals  Surfaces have chemical properties, which are different from bulk virgin material. o Most metallic surfaces in air have oxide layers, which change the chemical and mechanical properties of the surfaces.  Surfaces have mechanical properties, which are different from bulk material. o Machining or sliding contact makes strain hardened (or work hardened) layer and highly deformed layer, whose strength are different from bulk.  Real engineering surfaces are rough.
