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

Q1. Experiments were conducted in a tension testing machine to
evaluate the material properties of two metallic rods both having
diameter equal to 10 mm. First rod having modulus of rigidity of the
material equal to 400 tonnes/cm2 when subjected to an axial tensile
force of 6 kN, the change in its diameter was observed to be 0.0018
cm. The value for the bulk modulus of the second metallic rod is
same as that of the first one but modulus of elasticity 18% more.
Based on the material properties calculate and compare the values of
different moduli as well as Poisson's ratio for both metallic rods.
Justify your answer with reasons.

We have a grounded 2 cm in diameter steel shaft which is 10 cm in length connected to a rigid surface. This shaft is subject to the stresses at the tip point as given below; Tmean = 100 Nm, Talternating= 50 Nm, • Mmean = 30 Nm, Malternating = 40 Nm, Fmean = 4 kN, Faltemating= 6 kN. This shaft has minimum properties of Sy = 800 Mpa and Sut = 1000 Mpa. Assume; Kf for bending=1.5, Kf for tension = 1.4, and Kfs for torsion = 1.8. Using Modified Goodman criterion what can you say about the shaft? Does it have a limited life, if yes, how many cycles?
