Diagram shows an aluminum shaft A B with a support at A, marked 1 of length 1,500 millimeters and a brass shaft B C with a support at C, marked 2 of length 1,000 millimeters with a flange in between at B. The shafts are centered on the x axis. A torque T is applied at B.

In summary, the internal torques in shafts (1) and (2) are:

T1=424.63 N-mT2=-575.37 N-m

Shear stresses are:

τ1=29.30 MPaτ2=23.44 MPa

The rotation of flange B is:

ϕB=+0.02344 rad   =+1.34 deg
