The state of stress at a point under plane stress condition

Home » Strength Of Materials » Strength Of Materials Miscellaneous » Question

The state of stress at a point under plane stress condition is σ_xx = 40 MPa, σ_yy = 100 MPa and τ_xy =40 MPa The radius of Mohr's circle representing the given state of stress in MPa is

1. 40
2. 50
3. 60
4. 100

Correct Option: B

Here, σ_xx = 40 MPa; σ_yy = 100 MPa,
τ_xy = 40 MPa

√30² + 40² = 50 MPa
