Q2-) For the given 2D stress state [sigma_{x} au_{xy}; au_{xy} sigma_{y}] [MPa]; (Mega: x 10^6, Pa: N/m^2) a) Find the normal and shear stresses at the surface given with the normal at ? degrees. (?? and ??) b) Find the principal normal stresses ?_1 and ?_2 of the given stress state. c) Draw the Mohr's circle and indicate the reference point ? = 0 as well as the principal stresses.

Step 1
a) To find the normal and shear stresses at the surface given with the normal at \( \theta \) degrees, we can use the following equations: \( \sigma_{\theta} = \frac{\sigma_x + \sigma_y}{2} + \frac{\sigma_x - \sigma_y}{2} \cos(2\theta) - \tau_{xy} \sin(2\theta) Show more…

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)

The principal stresses at a point in a structural member are ́σ1 = 20 MPa, σ2 = 15 MPa, and σ3 = -10 MPa. Use Mohr's circle to determine the normal and shear stresses on an inclined plane defined by θ = 45° and ϕ = 60°.
