A thin rod consists of two parts joined together. One-third of it is silver and two-thirds is gold. The temperature decreases by 22 C°. ΔL/(L0,Silver + L0,Gold) Determine the fractional decrease in the rod's length using the formula above, where L0,Silver and L0,Gold are the initial lengths of the silver and gold rods. (See Table 12.1 for appropriate constants.)
1.A thin rod consists of two parts joined together. One-third of it is silver and two-thirds is gold. The temperature decreases by 24.7 C°. Determine the fractional decrease ?L/(LSilver + LGold) in the rod's length, where LSilver and LGold are the initial lengths of the silver and gold rods. 2.Equal masses of two different liquids have the same temperature of 20.5 °C. Liquid A has a freezing point of -68.5 °C and a specific heat capacity of 1840 J/(kg C°)....
(1) Two long fins Two infinitely long, metallic rods are joined together as shown in the figure. At the point that they are joined is a thin heat source with a known generation rate of in Watts. The two rods are surrounded by air with known h and T.. (a) Determine expressions for the temperature distribution in the rods in terms of symbols shown in the figure. (b) Determine expressions for the heat transfer rate into each of the two...
QUESTION 1 A dumbell consists of two identical masses of mass M attached to a either end of a rod of length 2X and of negligible mass. If the dumbell is rotated about an axis perpendicular to the rod and passing through the middle of the rod, as shown in the diagram. What is the rotational inertia of the dumbell?
