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.

Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.

Question

2. A metal alloy has been tested in a tensile test with the following results for the flow curve
parameters: strength coefficient = 620.5 MPa and strain-hardening exponent 0.26. The
same 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) 37.5
mm.
3. The starting length of a shaft is 25.00 mm. This shaft is to be inserted into a hole in an
expansion fit assembly operation. To be readily inserted, the shaft must be reduced in length
by cooling. Determine the temperature to which the shaft must be reduced from room
temperature (20° C) in order to reduce its length to 24.98 mm. Refer to the Table below.
