Question 2
The state of 2D–stress at a point is given by the following matrix of stress:
What is the magnitude of maximum shear stress(Radius of Mohr's circle) in MPa?
Question 3
In a two-dimensional stress analysis, the state of stress at a point is shown below. If σ = 120 MPa and τ = 70 MPa, then σx and σy are respectively. (AB=4, BC=3, AC=5)
Question 4
For the stress state (in MPa) shown in the figure, the major principal stress is 10 MPa.
The shear stress τ is
The shear stress τ is
Question 5
