A windmill turns a series of slender rods fixed about one end (see formula below). They are initially 2 meters long, and go at a speed of 15 rpm. I suggested making the blades 1m long to reduce the cross-sectional area of the windmill, keeping the mass the same for mechanical stress consistency. How fast are the windmill blades going now, in revolutions per minute?

Question

A windmill turns a series of slender rods fixed about one end (see formula below). They are initially 2 meters long, and go at a speed of 15 rpm.

I suggested making the blades 1m long to reduce the cross-sectional area of the windmill, keeping the mass the same for mechanical stress consistency.

How fast are the windmill blades going now, in revolutions per minute?
