The part shown in Figure P16.13 is to be pressed of iron powders using a compaction pressure of 75,000 lb/in2. Dimensions are in inches. Determine
(a) the most appropriate pressing direction,
(b) the required press tonnage to perform this operation, and
(c) the final weight of the part if the porosity is 10%. Assume that shrinkage during sintering can be neglected.
