Homework Statement A rotating disk of 2.50m in diameter serves tu connect a counter weight to a mass through a massless rope. The rope does not slip on the disk so, there is no friction on the rim. What angular velocity in rpm must the disk turn to raise the elevator at 25.0 m/s...

you were right, I am so sorry. thanks. I finally got it.!

I believe that's the equation when the axis of rotation goes through one of the bar's end. when the axis crosses the center of the bar I=1/3ML^2 according to my textbook.

Homework Statement A uniform bas has two small balls glued to its end, the bar is 2.00 m long, and it has a mass 4.00 Kg, while the balls, have mass 0.500Kg and can be treated as point masses. Find the moment of inertia of this combination about each of the following axes. a) an axis...
