Both solid circular shafts resist the applied torque T. The left shaft is C86100 Bronze with a radius of 7 cm, and the right shaft is 2014-T6 Aluminum with a radius of 5 cm. Determine the reaction at A. Give your answer using 4 significant digits and units of kN-m. Use JBronze = 3.771x10-5 m and JAluminum = 9.817x10-6 m. a + 2 m T=b+40 kN-m 3 m
