- 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
