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 1 You are working on a design team at a small orthopaedic firm. You have been asked to select a cobalt- chrome-molybdenum (CoCr) material that will not experience plastic deformation under a specific mechanical test, as follows... A tensile stress is applied along the long axis of a solid cylindrical rod that has a diameter of 10 mm. An applied load of some magnitude F produces a 7x10-³ mm change in diameter (see figure below, original shape is blue, elongated shape is unshaded). Q1A-B: Calculate the transverse strain in the x-direction (Ex) associated with the reduction in diameter. Calculate the axial strain in the z-direction (₂) associated with the length increase.
You are given three metal test samples, with the same chemical composition and differing grain sizes: A: 5.0, B: 10.0 and C: 20.0 microns. Samples A and B have been tested and have yield stresses of 142.4 MPa and 135.8 MPa (all numbers are rounded off to the 1st decimal point). Based on this information, which of the following values do you think will be the closest to the yield stress of Sample C? In calculating the answer, use the Hall-Petch relation between yield stress of a metal o vield and the grain size of the metal d, which is Oyield = 00 + kd¬1/2 where k and og are constants. (This question has only one correct answer) а. 100.6 MPa b. 131.1 MPa С. 152.4 MPa O d. 115.8 MPa е. 128.1 MPa
