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.

I need a clear answer by hand, not by keyboard and fast answer within 20 minutes. Thank you | dybala
I am only interested in part 6-27(a). I see that Bartleby has answered this question before but I have a question regarding the yielding factor of safety. Why is the yielding factor of safety calculated as ( n=Sy/sigma_max), but not as ( n=Sy/Kt*sigma_max )? Since there is a stress concentration factor and the sigma_max is technically considered the nominal stress.
In a bending test for a brittle material, the distance between the supports is 300mm, the cross sectional area of the specimen is 1200 and the thickness is 30mm. find the transverse rupture strength if the applied load was 1 ton.
A steel component is subjected to alternate cyclical loading. The steel follows Basquin's law for high cycle fatigue, o, x N = C, (where the stress amplitude is in MPa). Ignore the geometric detail and assume that Marin's modifying factors are all equal to 1. You are given the minimum stress ain = -213 MPa, the maximum stress omax = 213 MPa. The material data are Tensile strength oUTS = 539 MPa, Basquin's constant c, = 875 MPa, Basquin's exponent a = 0.085. a) Calculate the stress ratio R, the stress amplitude o, in MPa and the mean stress am in MPa. The answers are acceptable with a tolerance of 0.01 for R and of 1 MPa the stresses. R: MPa MPа b) Calculate the corresponding life, in 10° cycles, (tolerance of 0.1 106 cycles) N :
A rod specimen of ductile cast iron was tested in a torsion-testing machine. The rod diameter was 30 mm, and the rod length was 300 mm. When the applied torque reached 260.8 N·m, a shear strain of 1605 microradians was measured in the specimen. What was the angle of twist in the specimen?
Only the highlighted I need want to make sure I did it right
A steel rotating-beam test specimen has an ultimate strength, Sut, of 120 kpsi. Estimate the life of the specimen if it is tested at a completely reversed stress amplitude, Orev, of 74 kpsi. Take the value of the fatigue strength fraction, f, from Fig. 6-23. The life of the specimen is cycles.
Made of steel alloy whose engineering tensile curve is given in the figure below, 10 mm diameter and 75 mma tall cylindrical specimen;a) Find the yield strength (0.2% limit).b) Calculate the maximum load it can carry.c) Calculate the elongation that occurs in the length when a load of 20000 N is applied to the sample.
Tensile and fully reversed loading fatigue tests were conducted for a certain steelalloy and revealed the tensile strength and endurance limit to be 1200 and 550 MPa,respectively. If a rod of this material supply were subjected to a static stress of 600MPa and fully-reversed oscillating stresses whose total range was 700 MPa. Assuming garber relationship will this rod fail by fatigue failure
