A 40.0-g projectile is launched by the expansion of hot gas in an arrangement shown in Figure P12.4a. The cross sectional area of the launch tube is 1.0 cm2, and the length that the projectile travels down the tube after starting from rest is 52 cm. As the gas expands, the pressure varies as shown in Figure P12.4b. The values for the initial pressure and volume are P1 = 11 105 Pa and Vi = 8.0 cm3 while the final values are Pf = 1.0 105 Pa and Vf = 8.0 cm3. Friction between the projectile and the launch tube is negligible, (a) If the projectile is launched into a vacuum, what is the speed of the projectile as it leaves the launch tube? (b) If instead the projectile is launched into air at a pressure of 1.0 105 Pa. what fraction of the work done by the expanding gas in the tube is spent by the projectile pushing air out of the way as it proceeds down tile tube?

A student foolishly attempts to stop a steel bar, of length L = 1 m and at a temperature of 20ºC, from thermally expanding by attaching it to a wooden support with a nail at each end. Steel's Young's modulus is Y = 1.1 × 1011 N/m2 and it's linear thermal expansion coefficient is α = 13 × 10-6 1/C. Randomized Variables Y = 1.1 × 1011 N/m2α = 13 × 10-6 1/C What is the volue of the stress, in pascals, that develops due to a rise of temprature to 21 C?

You are using a thin layer of epoxy to bond a Silicon chip to a pure aluminum plate that acts as a heat sink (epoxy layer 0.0200mm). The Silicon chip (k = 149.0 W/(m-K) is 0.200 mm thick, and has dimensions of 25.0mm by 25.0mm. The pure aluminum plate is 0.850cm thick, and has the same dimensions as the Silicon chip. The hot side of the silicon chip is measured to be 62.0°C; the cold side of the pure aluminum plate is measured to be 31.0°C. Assuming steady-state conduction (with the thin layer of epoxy acting as contact resistance, see Table 3.2.) determine the heat transfer rate through the chip. Do not add in an addition resistance due to the thickness of the epoxy layer, this has been incorporated into the contact resistance.

1. A length of nylon fishing line of 2 mm diameter is tied to a length of 0.5 mm diameter stainless steel wire, then stretched between two rigid supports 2 m apart such that the tension in the wires is 20 N and the connection point between the two wires is exactly midway between the posts. The air temperature then goes down by 20°C. Find the distance that the connection moves. [Youngs modulus for nylon is 3 GPa, its thermal expansion coefficient is 6×10−5/K. Youngs modulus for stainless steel is 180 GPa, its thermal expansion coefficient is 1.7 × 10−5/K.]
A particle on the surface of the Earth can "escape" the Earth's gravitation and continue to move away from the Earth forever, if it has a sufficient speed (called the escape speed). (a) Determine the escape speed (in m/s) if the particle is an oxygen molecule. Use 6.37 x 106 m for radius of the Earth. m/s (b) Determine the temperature (in K) at which the rms speed of the oxygen molecule is 13 times the escape speed. T = K (c) What If?
