minus-square@ReluctantMuskrat@lemmy.worldlinkfedilinkEnglish14•1 year agoI’d like to know how many rpms that is and the speed that equates to when it starts deforming and when it flies apart.
minus-square@agent_flounderlinkEnglish10•1 year agoBased on 45k rpm mentioned in another comment and picking, idk, a 52mm diameter wheel (they range from 48-60) that’s 163mm circumference. 45k rev/m x 60 m/h x 163mm/rev x 1km/1e6mm = 440kmh = 273mph. (I probably messed up something but idk)
