Test No. VNL10 Find the rotation of cylinder subjected
to a moment of 10 N-m along its length.
Definition
The cylinder is connected to a grounded spring with the following stiffness:
X
100 N/m
Y
100 N/m
Z
100 N/m
Rot X
10 N-m/rad
Rot Y
10 N-m/rad
Rot Z
10 N-m/rad
The units are SI.

Results
Grounded bushing with above referenced stiffnesses is applied on one end of the
cylinder and a remote load of 10 N-m about the cylinder axis is applied on the other
end, as shown in Figure 2. Figure 2.
Datum points are created along the circumference of the cylinder. Rotation between
the points is measured to calculate the rotation of the cylinder due to applied
moment load. Figure 3.
The following table summarizes the rotation of the cylinder.

*The reference is calculated by hand using a rotation of 1 radian about the cylinder
axis.
