A steel water pipe, of inside diameter 25 mm and outside diameter 30 mm, isrigidly attached at two points along its length to a concrete wall. The forceexerted on the pipe by the fastenings is zero on a hot day, when both pipe andwall are at 30°C. On a cold day, when the wall is at 10°C and the pipe hasbeen heated by water passing through it, the compressive force exerted on thepipe is (30 kN.) Calculate the temperature of the pipe.Assume that stresses due to the pipe do not affect the contraction of the wall.Coefficient of linear expansion for concrete = 6.10 °C.Coefficient of linear expansion for steel = 1,1.10-5 °C-1Young's modulus for steel = 2.10" N.m².

The moment of inertia I of a uniform rod rotating around its center point is I = 1/12ml^2 where m is the mass of the rod and l is its length. (A) Derive an expression for the change in the moment of inertia for such a rod, ΔI, that includes the initial moment of inertia I0, the coefficient of linear expansion  for the rod material, and a temperature change ΔT. (B) A uniform rod of mass 0.500 kg and length 1.000 m at T = 0 °C rotates around its center in free fall (e.g., floating in a space station) at an angular velocity of exactly 1 radian per second. If it is warmed to 30 °C and = 20 × 10  −6 °C−1, what would its angular velocity be? Use conservation of angular momentum.

Perfect vacuum refers to a region that is completely devoid of particles. Pressure in perfect vacuum would be zero. On Earth, achieving a perfect vacuum is quite difficult in practice. In a modern physics laboratory with state-of-the-art vacuum systems, one may achieve a pressure of 1 nPa (1 × 10-9 Pa). This is referred to as ultra-high vacuum. Suppose you have a vessel of volume 1 m³ filled with air at a temperature of 300 K (approximately room temperature). Suppose a vacuum system is used to pump air out of the vessel, reducing the pressure from an initial value of 101325 Pa (1 atm) to a final value of 1 nPA. Assume that the volume and temperature remain constant. Calculate the initial and final numbers of molecules in the vessel at atmospheric pressure and at ultra- high vacuum (1 nPa). Comment: Perhaps surprisingly, even at ultra-high vacuum there is still a large number of particles in the vessel: 0 « N; « N;.
