14-50. Determine (2) the principal stresses and (b) the maximum in-plane shear stress and average normal stress Specify the orientation of the element in each case. во MPа 60 MPa

Thank you in advance, note it ask for stress a B

Question: Find schematically the normal and shear stresses in the plane when the element in the plane stress state is rotated 30 degrees counterclockwise with the Mohr circle.

Determine (a) the principal stresses and (b) the maximum in-plane shear stress and average normal stress. Specify the orientation of the element in each case.

6 The principal stresses at a point on a plane are 01 = 50, O2 = 40 and O3 = - 20 MPa Determine the normal and shear stresses on this plane if its direc- 1 tion cosines are 2 V14' J4' J14

Knowing that the bracket AB has a uniform thickness of in and that P-5 kips, determine (a) the principal planes and principal stresses at point K and (b) the maximum sheanng stress at point K (Round the final answers to two decimal places. Input the answers with the appropriate sign) 25 im 2in (a) The principal stresses are Omax"41565 Oksi at Omin"13855 24 iksi at 24 (b) The maximum shearing stress is 2.771 Iksi.

The state of stress at a point is shown on the element. Determine (a) the principal stresses and (b) the maximum in-plane shear stress and average normal stress at the point. 160 MPa 120 MPa
