mohr's circle 1

What kind of loading conditions is Mohr's Circle primarily used for?

• Dynamic loading conditions
• Three-dimensional stress states
• Two-dimensional stress states

• Thermal loading conditions

Mohr's Circle helps in determining the stresses on which type of planes?

• Mohr's Circle can only determine stresses on horizontal planes.
• Planes under pure shear stress

• Any inclined plane at a point in the material

• Mohr's Circle only applies to vertical planes.

How does the radius of Mohr's Circle relate to the maximum shear stress?

• The radius of Mohr's Circle is unrelated to shear stress.
• The radius of Mohr's Circle is the maximum principle stress.

• The radius of Mohr's Circle is equal to the maximum shear stress.
• The radius of Mohr's Circle is equal to the average normal stress.

If σ1 = σ2 = σ, what is the radius of Mohr's Circle

• σ
• 1
• 0
• σ/2

When applying Mohr's Circle, the angles represented on the circle are:

• The angles represent the material properties of the object.
• Irrelevant to the physical angles

• Double the actual angles in the material

• The same as the actual angles in the material

Which of the following Mohr’s Circle represent the condition of pure uniaxial tension?

• 
• 
• 
• 

When σ₁>0and σ₂<0, how does Mohr's Circle visually represent the state of stress?

• The circle lies entirely in the positive stress region

• The circle lies entirely in the negative stress region

• The circle intersects both positive and negative stress regions

• The circle cannot be drawn in this scenario.

When can a Mohr's Circle collapses to a point, indicating hydrostatic stress.

• When the material is inelastic.
• mohr's circle cannot collapse

• When one principal stress is significantly higher than the others.
• When all principal stresses are equal.

If Mohr's Circle intersects the τ-axis, what type of stress state exists

• A state of triaxial stress.
• A state of pure normal stress

• A state of pure shear stress.
• A state of hydrostatic stress.

In a scenario where σ₁=30 MPa, σ₂=−50 MPa, what will be the position of the center of Mohr's Circle?

• -30 MPa
• -10 MPa
• 20 MPa
• 0 MPa
