Mohr Circle 3

The normal stresses at a point are σ_x = 10 MPa and, σ_y= 2 MPa; the shear stress at this point is 4MPa. The maximum principal stress at this point is:

• 16 MPa

• 14 MPa

• 11 MPa

• 10 MPa

Solve the problems and choose correct answers. The state of stress at a point "P" in a two dimensional loading is such that the Mohr's circle is a point located at 175 MPa on the positive normal stress axis.

Determine the maximum and minimum principal stresses respectively from the Mohr's circle

• + 175 MPa, –175MPa

• + 175 MPa, +175MPa

• 0, –175MPa

• 0,0

In the above question

Determine the directions of maximum and minimum principal stresses at the point “P” from the Mohr's circle

• 0, 90°

• 90°, 0

• 45°, 135°

• All directions
