As shown in the diagram, a bead slides on a wire which is in a vertical plane (i. e. perhaps in the plane of your computer screen). Gravity acts in the -y direction (down). The bead starts at A and moves to the right with an initial velocity v. The wire is frictionless between A and D and also between F and G, but there is friction between D and F. For each statement select True, False, Greater than, Less than, Equal to, or Not enough information to tell.

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.
