Anti-Gravity Wheel?


Description:

Explanation of gyro precession: : Than: To: thanks to A/Prof Emeritus Rod Cross, Helen Georgiou for filming, Alex Yeung, and Chris Stewart, the University of Sydney Mechanical Engineering shop, Duncan and co. Ralph and the School of this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it's spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was 'light as a feather' and could not be explained by Newton's Laws. I wanted to find out for myself what I really felt By Kevin MacLeod "Tempting Secrets"

    The weight stays the same, when the wheel is not rotating you must not only lift the wheel up but also apply downward pressure on the other end of the shaft in order to hold it level. When it is spinning you no-longer need to apply that downward pressure so the whole assembly feels lighter.

    I wonder if he weighed less? my guess would be greater than with the centrifugal force pushing down as well as all directions. But the scale will only measure the downward pressure.
