For the plane stress states listed below, draw a Mohr's circle diagram properly labeled, find the principal normal and shear stresses, and determine the angle from the x axis to $\sigma_1$. $\sigma_x = 20$ kpsi, $\sigma_y = -10$ kpsi, $\tau_{xy} = 8$ kpsi cw

Step 1
Step 1: The center of the Mohr's circle is located at the average of the normal stresses: $$C = \frac{\sigma_x + \sigma_y}{2} = \frac{20 - 10}{2} = 5 \text{ kpsi}$$ Show more…

For each of the stress states listed below, find all three principal normal and shear stresses. Draw a complete Mohr's three-circle diagram and label all points of interest. (a) σx = -80 MPa, σy = -30 MPa, τxy = 20 MPa cw (b) σx = 30 MPa, σy = -60 MPa, τxy = 30 MPa cw (c) σx = 40 MPa, σz = -30 MPa, τxy = 20 MPa ccw (d) σx = 50 MPa, σz = -20 MPa, τxy = 30 MPa cw
Draw the Mohr's Circle of Stress for the given state of stress at a point (5 pts) and determine the following: (a) Principal Stresses – 4 pts (b) Maximum In-Plane Shear Stress – 2 pts (c) Normal and Shear Stresses on the plane defined by x'-axis (oriented as shown) – 4 pts GIVEN: Αx = +150 Mpa Αy = +100 Mpa Αxy = 75 Mpa Θ = 30 degrees (x'-axis orientation)
