3 - A torque of 2000 N-m is applied on a steel circular shaft with a diameter of 50 mm. The shaft has a length of 2 m. The Young's modulus and Poisson's ratio of the steel are E = 200 GPa and ✓= 0.3, respectively. What is the maximum shearing stress? What angle of twist occurs over the length of the shaft?

None

Two solid steel shafts are fitted with flanges that are then connected by bolts as shown. The bolts are slightly undersized and permit a 1.5° rotation of one flange with respect to the other before the flanges begin to rotate as a single unit. Knowing that G=77.2 GPa, determine the maximum shearing stress in each shaft when a torque T of magnitude 580 N-m is applied to the flange indicated. The torque T is applied to flange C. (Round the final answers to two decimal places.) 30 mm 600 mm B 36 mm T = 500 Nm 900 mm The maximum shearing stress in shaft AB is The maximum shearing stress in shaft CD is MPa. MPa.
