. When the space shuttle is launched from Earth, the rocket engines burn fuel and
apply a constant force on the shuttle until
they burn out. Explain why the shuttle's
acceleration increases while the rocket
engines are burning fuel.

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.
