High Speed Shaft Growth
High Speed Shaft Growth
(OP)
Can anyone provide me with a plug-n-play equation for determining the increase in diameter for a solid shaft spinning at an extreme high speed due to hoop stress, 9or centrifugal force)? Thanks.

For a solid shaft :
Change in outer radius - in
delR = den/4*omega^2/386.4*R^3/E*(1-nu)
where den = density lb/in^3
omega = angular velocity rad/sec
R = outer radius in
E = Youngs modulus lb/in^2
nu = Poisson's ratio
