WebNov 20, 2013 · The Attempt at a Solution. I started by taking a point mass of the rectangle to be the distance r from the center. This point would have the mass dm. dm would then equal λdA. λ would equal M/A or M/ab. dA would be the area of the small point. I'm guessing this would be dydx. So, for dm we have (M/ab) (dydx) Now for r 2. WebSep 17, 2024 · The dimensions of the ring are Ri = 30 mm, Ro = 45 mm, and a = 80 mm. Answer. Solution.
