And the normal force from the spring will be:
Combining the above equations and solving for the spring
force we get:
From the spring force and by defining a design deflection
for the spring, a spring constant can be determine:
Deflection of the spring:
Therefore it appears that a very large spring constant
would be needed for this design.

With a given torque limit:
A tangential force will result on the end of the shaft
depending on the location that we wish to analyze.
For a given radius:
The Force located at this point on the
shaft can be calculated using the equation:
The geometry of the design will place a normal force
on each protrusion from the force of the spring, and
from the torque of the shaft. During normal operation
these forces must balance each other to avoid slipping.
During an overloading condition, the force from the
torque should be larger than the force from the spring.
Given an angle of the disk with respect to the axis
perpendicular to the axis of rotation of the shaft:
