The state of stress at a point is the result of two loadings as shown in figure. When acting alone, the first loading produces the 3 MPa pure shear with respect of xy-axis. The second loading alone results in the 4 MPa pure shear with respect to the x'y-axis. The angle between the two sets of axis is 30° as shown. If the two loadings act simultaneously then resultant (absolute) shear stress at that point with respect to x-y axis is MPa (in integer). 3 MPa st 1 loading 2 loading 4 MPa α = 30° x'

Which of the following is correct regarding the principal stress and maximum in-plane shear stress? a) The shear stress over principal stress planes is zero, b) The maximum in-plane shear stress is always smaller than the principal stresses, c) A principal stress plane can be reached by rotating the maximum in-plane shear stress plane 90 degrees in the clockwise direction, d) Principal stress can not be negative.
At a particular point in a structural member a direct tensile stress of 60 N/mm² exists on a plane perpendicular to the longitudinal axis of the member while a direct compressive stress of 40 N/mm? occurs on a plane parallel to this axis; in addition shear and complementary shear stresses of 50 N/mm? act on these planes. If Young's modulus E is 200000 N/mm² and Poisson's ratio v is 0.3 calculate the direct and shear strains on these planes and hence, using a graphical method, determine the principal strains at the point, the maximum shear strain and the angle the plane of maximum principal strain makes with the longitudinal axis of the member. Finally, calculate the principal stresses at the point. Ans. E= 3.6x104, ɛ, = -2.9x104, Yy=6.5x10-4 ɛ1 = 4.95x10, 01 = 80.8 N/mm², o1=-60.8 N/mm. Ɛ11 =-4.25x10 Ymax=9.2x10-, 67.5°
