Problem 6.21 An aluminum alloy extruded section is subjected to a torsional load. Determine the maximum torquesthat can be applied to the member if the maximum shear stress is 75 MPa. Neglect stressconcentrations at changes in the section.Solution:95 mm 140 mm10 mm 5 mm85 mm 15 mmb195 mm⋅2:=h15mm⋅2:=b1h119=b2140 mm⋅2:=h210 mm⋅2:=b2h214=b385 mm⋅2:=h315 mm⋅2:=b3h35.667=Since b/h < 10
