MecMovies 4.0 : M6.20: Shear Stresses in End-to-end Shafts

scene 6 of 14

Diagram shows an aluminum shaft A B with a support at A and a brass shaft B C with a support at C with a flange in between at B. The shafts are centered on the x axis. A torque T is applied at B.

Torque $T$ applied at flange $B$ causes both shafts to twist. While the supports prevent rotation at $A$ and $C$ , the shaft rotates through an angle of $ϕ_{B}$ at the flange.
