Please construct a Mohr’s circle for the state of plane-stress element at a point as shown in Fig 3. Determine the principal stresses σ1 and σ2 on this point and show them on a sketch of a properly oriented element. σx=60 MPa, σy = 0 MPa, τxy = 40 MPa.
For each of the plane stress states listed below, draw a Mohr's circle. Find the principal
normal and shear stresses and determine the angle from the x-axis to σ1.
=
(a) σx -8 MPa, σy
=
7 MPa, Txy
=
6 MPa cw
(b) σx = 9 MPa, σy = −6 MPa, Txy
=
3 MPa cw
(c) σx = −4 MPa, σy
=
12 MPa, Txy
=
7 MPa ccw
Mohr’s circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 16 MPa in size. (a) Determine the stresses σx, σy, and the magnitude of τxy and show them on a stress element. (b) Determine the stresses σn, σt, and the magnitude of τnt and show them on a stress element that is properly rotated with respect to the x-y element. The sketch must include the magnitude of the angle between the x and n axes and an indication of the rotation direction (i.e., either clockwise or counterclockwise).
