Test: Analysis of Stress & Strain - 3 - Mechanical Engineering MCQ

The state of stress at a point in a body under plane state of stress condition is given by MPa . The maximum shear stress (in MPa) is

If at a point in a body σ_x = 70 MPa, σ_y = 60 MPa and τ_xy = - 5 MPa, then the radius of Mohr’s circle is equal to

The state of stress at a point in a loaded member is shown in figure below. The magnitude of maximum shear stress is

The cross-section of a bar is subjected to a uniaxial tensile stress 'p' The tangential stress on a plane inclined at θ to the cross-section of the bar would be

The figure shows the state of stress at a certain point in a stressed body. The magnitudes of normal stresses in the x and y directions are 100 MPa and 20 MPa respectively. The radius of Mohr’s stress circle representing this state of stress is
