Two Triangular wedges are glued together as shown in the following figure. The stress acting normal to the interface, ${\sigma}_{n}$ is __ MPa.
For the plane stress situation shown in the figure, the maximum shear stress and the plane on which it acts are:
The state of 2D-stress at a point is given by the following matrix of stresses:
$\left[\begin{array}{cc}{\sigma}_{xx}& {\sigma}_{xy}\\ {\sigma}_{xy}& {\sigma}_{yy}\end{array}\right]=\left[\begin{array}{cc}100& 30\\ 30& 20\end{array}\right]MPa$
What is the magnitude of maximum shear stressin MPa?
consider a simply supported beam with a uniformly distributed load having a neutral axis (NA) as shown. For points P (on the neutral axis) and Q (at the bottom of the beam) the state of stress is best represented by which of the following pairs?
The major and minor principal stresses at a point are 3 MPa and -3 MPa respectively. The maximum shear stress at the point is
Consider the following statements:
I. On a principal plane, only normal stress acts. II. On a principal plane, both normal and shear stresses act. III. On a principal plane, only shear stress acts. IV. Isotropic state of stress is independent of frame of reference.
The TRUE statements are
An axially loaded bar is subjected to a normal stress of 173 MPa. The shear stress in the bar is
