Problem 6.59 Given: A wide flange steel I-beam is 8.0 m long and dimensions shown. The I-beam is fixed at one end and free at the other end. A twisting moment of 7 kN-m is applied at the free end. Determine the maximum normal stress and maximum shear stress in the I-beam and the rotation of the free end. Solution: 300 mm 270 mm 20 mm 15 mm E 200 GPa := G 77.5 GPa := L 8m := T 7000 N m := I min 220 mm 270 mm () 3 12 260 mm 15 mm 3 12 + := I min 6.568 10 5 × m 4 = J 1 3 2 270 mm 20 mm 3 260 mm 15 mm 3 + 1.733 10 6 × m 4 = := h 280 mm := α h 2 EI min JG := α 1.385 m
