GATE (CE) : STRENGTH OF MATERIAL #6 (App update required to attempt this test)

Two triangular wedges are glued together as shown in the following figure. The stress acting normal to the interface, σ_n is _____ MPa.

If the principal stresses at the point C due to the loading as shown in the figure below is x and y MPa then the absolute value of 2x+y is

For a plane stress problem, the state of stress at a point P is represented by the stress element as shown in the figure.

By how much angle (θ) in degrees the stress element should be rotated in order to get the planes of maximum shear stress?

Two triangular wedges are glued together as shown in the following figure. The stress acting normal to the interface, σ_n is _____ MPa.

A link is under a pull which lies on one of the faces as shown in figure below. The magnitude of maximum compressive stress in the link would be _______ N/mm².
