The state of stress at a point on an element is shown in figure (a). The same state of stress is shown in another coordinate system in figure (b).
The components $\style{font-family:'Times New Roman'}{\left(\tau_{xx},\tau_{yy},\tau_{xy}\right)}$ are given by
The state of sttress at a point is given by ${\sigma}_{x}=-6$ MPa, ${\sigma}_{y}=4$ MPa, and ${\tau}_{xy}=-8$ MPa.The maximum tensiile stress (in MPa) at the point is ________
The state of stress at a point under plane stress condition is
${\sigma}_{xx}=40MPa,{\sigma}_{yy}=100MPa$ and ${\tau}_{xy}=40MPa$
The radius of the Mohr’s circle representing the given state of stress in MPa is
The state of plane-stress at a point is given by σ_{x} =−200MPa, σ_{y} = 100MPa and $\tau $= 100MPa . The maximum shear stress in MPa is
If the principal stresses in a plane stress problem are ${\sigma}_{1}$ = 100 MPa,${\sigma}_{2}$ = 40 MPa, the magnitude of the maximum shear stress (in MPa) will be
A two dimensional fluid element rotates like a rigid body. At a point within the element, the pressure is 1 unit. Radius of the Mohr’s circle, characterizing the state of stress at the point, is
