MecMovies 4.0 : M6.22: Maximum Torque Applied to Coaxial Shaft

scene 14 of 14

Diagram shows a shaft A B with an aluminum segment on the outside and a brass shaft in the inside. Both the shafts are centered on the central axis x. A torque T is applied at B. The radial and longitudinal lines are shown on the shaft. The deformation of the shaft is shown with a counterclockwise segment of angle phi subscript B, angle of twist.

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

$T_{1} = 1,003.8 N-m T_{2} = 1,076.0 N-m$

Shear stresses are:

$τ_{1} = 81.45 MPa τ_{2} = 100 MPa$

The rotation of end $B$ is:

$ϕ_{B} = + 0.05012 rad = + 2.87 \deg$
