Unformatted text preview: = 60 o , find the normal and shear stress components transmitted across the weld line when the tube transmits a torque T = 1 kN m in the direction shown. T T α welds Figure 3 4. Figure 4 shows the stresses acting on an element of material. Sketch Mohr’s circle for this state of stress and hence determine the principal stresses σ 1 , 2 and the inclination of the planes on which they act. Illustrate your answer by sketching a rotated rectangular element of which the faces are principal planes, showing which principal stress acts on each face. 18 MPa 72 MPa 36 MPa 18 MPa 72 MPa 36 MPa Figure 4 2 5. Figure 5 shows the stresses acting on an element of material.
