Answer
For isotropic material plastic yielding depends upon magnitude of the principle stress not on the direction.
Tresca and Von Mises yield criteria are the yield model which is widely used.
The Tresca yield criterion stated that yielding will occur in a material only when the greatest maximum shear stress reaches a critical value.
max{|σ₁ - σ₂|,|σ₂ - σ₃|,|σ₃ - σ₁|} = σ_f
under plane stress condition
|σ₁ - σ₂| = σ_f
The Von mises yielding criteria stated that the yielding will occur when elastic energy of distortion reaches critical value.
σ₁² - σ₁ σ₂ + σ₂² = σ²_f
Answer:
D. Rectangular
Explanation:
This is because rectangular coordinate systems are used in plotting common straight lines graphs with the formulae,
Y = Mx + c
Where y is the vertical coordinate
X is the horizontal coordinate
M is the dlope of the line
C is the y-axis intercept
Answer:
I have 72 baes just kidding I have 73 but they all don't love me
Answer:
Independent, dependent
Explanation:
The mediation conditions are what affect anxiety hence anxiety is dependent on mediation. The main aim of the researcher is to see how anxiety levels of people vary depending on the meditation. In this case, meditation conditions are independent variables. Therefore, it's proper to conclude that the meditation vs no meditation conditions are independent variables while anxiety is dependent variable
