A company is
bidding for a contract to produce 10,000 clevis blocks or chain adaptors used
in aerial lifts (cherry pickers). The machine drawing for this steel component
is indicated in Fig. 9-10. Specifications call for a hardness value of Re 46 at
the indicated point. Otherwise the choice of the material is left to the
manufacturer, cost being the only consideration. The only steel on hand is 1040
and a quick decision as to which steel to use is required.
