The flow limit of commercial-grade aluminum is given as σ = 120
MPa, the modulus of elasticity is E = 70 GPa and the density is 2.7
gr / cm3.
a) There is a 4mm diameter and 3m long wire which made with this
material. How many N should be applied to make this wire 3mm
longer?
b) If a 4 mm diameter wire made of this material is hung from the
ceiling, what should be the total length of...

A lot of the material I find myself relating to my son sorry if
this seems a bit repetitive but I feel that this discussion board
too can be related to my nine month old son. I have found it so
amazing as my son has developed that he has known my voice as his
mother. I think that part of it is the nurture factor that I have
been there for him consistently in the sense...
An isotropic sample of a material is subjected to a compressive
stress of 230 MPa in the x direction. However, it is confined so
that the sample cannot deform in the y and z directions. Data:
Young’s modulus of the block E = 46 GPa Poisson ratio υ = ⅓ Height
= 0.5 m Width = 0.5 m Length = 0.5 m Calculate these stresses in
the y- and z-directions (in MPa to 2 decimal places) Calculate the
strain in...
Young's modulus is a quantitative measure of the stiffness of an elastic material. Suppose that for aluminum alloy sheets of a particular type, its mean value and standard deviation are 70 GPa and 1.6 GPa, respectively (values given in the article "Influence of Material Properties Variability on Springback and Thinning in Sheet Stamping Processes: A Stochastic Analysis" (Intl. J. of Advanced Manuf. Tech., 2010: 117-134)).(a) If X is the sample mean Young's modulus for a random sample of n =...

Aluminum oxide (Al2O3) has an elastic modulus of 400 GPa and a
KIc of 4 MPa•m1/2 . A specimen is tested in tension and is found to
deform elastically up to the point of fracture at a stress of 450
MPa. (a) Make a diagram of engineering stress-engineering strain to
show this behavior. (b) Find the strain at fracture. (b) Estimate
the flaw size (a) that caused failure (assume Y = 1). (c) If
another specimen of the same size...
We Will Choose An Iron Based Material
average tensile 50 Mpa (material
We will calculate Sigma D, Re, Rm, Stress Amplitude and Maximum Stress.
How much tensile amplitude can the haight diagram max tensile
(I need the table and values in any sample that I will
determine myself. values can be matched.)
(can be ready example just back down to 50Mpa)
At a tensile strength of 1000 MPa, the material with the lowest
embodied energy is
titanium alloys
high carbon steel
nickel-based superalloys
tungsten alloys
