What Happens When a Spinning Object's Radius Becomes Zero?

    Radius Spinning
AI Thread Summary
When an object's radius approaches zero, it is theorized that it would begin to rotate around its axis to conserve kinetic energy. This transformation from translational to rotational motion raises questions about the mechanics involved. Initial speed can be maintained at 100 m/s indefinitely if friction is neglected, according to conservation of energy principles. However, significant work is required to achieve this reduction in radius and to effectively gear the system. The discussion emphasizes the need for a solid understanding of physics to grasp these concepts accurately.

my educated guess is that with 0 radius the object would start rotating around the axe to keep the kinetic energy

this would mean a transformation of translation into rotation

am i correct?

First off you had to do a heck of a lot of work to reduce the radius.
 
not really if you crank the spinning with the pulling by gearing the axe with the radius bar

you apport a initial speed of 100 m/s to the object and according conservation of energy the object should keep those 100 m/s for ever (neglecting friction)

the bar radius would be geared with the axe transforming the spinning into pulling
 
i don't care how you gear it you have a lot of work to do.

Please take a break from your wild imagination and go find a physics book.
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
