Question

Two triangular wedges are glued together as shown in the following figure. The stress acting normal to the interface, σn\sigma_n is __________ MPa.
A square element with normal stresses of 100 MPa. The horizontal stresses are tensile (arrows pointing away from the vertical faces) and the vertical stresses are compressive (arrows pointing towards the horizontal faces). An interface is shown at an angle of $45^\circ$ with the horizontal, and $\sigma_n$ is the normal stress acting on this interface.
