The state of plane stress at a point is represented on the element shown in the figure below. (a) Determine the principal stresses acting on this point, and the corresponding orientation (angle). (b) Determine the maximum in-plane shear stress, and the corresponding orientation (angle). Also determine the associated average normal stress. Draw Mohr's circle and show the stresses on the circle.

fill in the blank please Tensile normal stresses are considered positive in Mohr’s circle. For the specific stress element face, if the shear stress makes the element rotate clockwise, then the normal stress is drawn (          )   the σ axis.

The diagram below  shows Mohr’s circle for a point in a physicalobject that is subjected to plane stress.(a) Determine the stresses σ x, σ y, and τ xy, and show them on astress element.(b) Determine the principal stresses and the maximum in-planeshear stress acting at the point, and show these stresses on anappropriate sketch

A structural member is subjected to the plane stress condition. The state of stress at a point of the member is shown in the figure. 45 MP (1) Draw the Mohr's circle for this 2D state of stress. (2) Determine the principal stresses, the maximum in-plane shear stresses and associated normal stresses acting at this point, (3) Represent these critical stresses on new stress elements, and indicate the angles of rotation of the new stress elements with respect to the original stress elements. 25 MP
