2. A metal alloy has been tested in a tensile test with the following results for the flow curveparameters: strength coefficient = 620.5 MPa and strain-hardening exponent 0.26. Thesame metal is now tested in a compression test in which the starting height of the specimen= 62.5 mm and its diameter = 25 mm. Assuming that the cross section increases uniformly,determine the load required to compress the specimen to a height of (a) 50 mm and (b) 37.5mm.3. The starting length of a shaft is 25.00 mm. This shaft is to be inserted into a hole in anexpansion fit assembly operation. To be readily inserted, the shaft must be reduced in lengthby cooling. Determine the temperature to which the shaft must be reduced from roomtemperature (20° C) in order to reduce its length to 24.98 mm.
