The principal stresses at a critical point in plane stress are o and 0.250. The yield stress for the material is oy = 250 MPa. The magnitude o that will cause yielding according to the maximum distortion energy theory is_MPa. (Correct up to two decimal places)

Learning Goal: The state of in-plane stress at a point on an element of material is shown. Let o = 55.0 ksi, oy = 16.0 ksi and Try = 10.0 ksi. Use this information to represent the state of stress of the same point that is rotated through an angle of 0 = 35° b b OT ▼ Part A - Normal and shear stress on element sectioned at plane a a Using the element sectioned at plane a-a and the rotated coordinate system shown, determine the normal and shear stresses, or and Try, respectively, acting on plane a-a ▼ Part B - Normal and shear stress on element sectioned at plane b-b Using the element sectioned at plane b-b and the rotated coordinate system shown, determine the normal Or Try and shear stresses acting on plane b-b. Express your answers in ksi to three significant figures separated by a comma. View Available Hint(s) VE ΟΙ ΑΣΦΑΛΙ b vec 0 ksi

The state of stress at a given point is given in the following figure. Use Mohr’s circle to find: a) The principal stresses b) The maximum in-plane shear stresses. For both cases you must draw a rotated element including all stresses and the angle of rotation. You must draw a properly labeled Mohr’s circle.

Calculate the main stress plane and main stress at the plane stress conditions as shown in the following figure.
