- total mega pascals that can be applied to a spinning flywheel before it exceeds its tensile strength

I'm wonder how one could calculate the total mega pascals total mega pascals that can be applied to a spinning flywheel before it exceeds its tensile strength

example: a cast iron flywheel is spinning at 10,000rpm(Tangential velocity = 104.72) it has a radius of 100mm and a weight of 500g

Typical tensile yield strength of cast iron is 428 MPa

Typical ultimate tensile strength of cast iron is 497 MPa

The equation for centrifugal force is F = (m x v²) / r

m = 500g

v = 104.72m/s

r = 100mm

so according to these numbers Force = 54.83kN, Centrifugal Acceleration = 109.66kM/s²

F = (500 x 104.72²) / 100

F = (500 x 10966.28) / 100

F = (5483139.2) / 100

F = 54831.392
