The torques shown are exerted on pulleys A, B, and C. Knowing that both shafts are solid, determine the maximum shearing stress in (a) shaft AB, (b) shaft BC.
a) 97.21 MPa; 56.36 MPa
b) 94.38 MPa; 71.66 MPa
c) 85.14 MPa; 93.27 MPa
d) 78.32 MPa; 49.52 MPa
Word document attached shows how to find the maximum shearing stress in two pulley shafts.
