At 20βc, 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 12Γ10β6 kβ1 and23Γ10β6 kβ1 respectively.

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 β 103 m/s and sticks, given the collision lasts 6.00 β 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
