The ends A and B of a rod I c.m. long have their temperatures kept at 30.C and 8CoC, until steady state conditions prevail. The temperature of the end B is suddenly reduced to 60"C and that of A is increased to 40"C. Find the temperature distribution in the rod after time

The two ends of an iron rod are maintained at different temperatures. The amount of heat that flows through the rod by conduction during a given time interval does not depend upon A-the duration of the time interval. B-the mass of the iron rod. C-the length of the iron rod. D-the thermal conductivity of iron. E-the temperature difference between the ends of the rod.

Heat equation: Arbitrary temperatures at ends. If the ends x = 0 and x = L of the bar in the text are kept at constant temperatures U1 and U2, respectively. The initial temp distribution is given by u(x, 0) = f (x). (a) What is the temperature u1(x) in the bar after a long time (theoretically, as t → ∞)? First guess, then calculate. (b) What is the temperature at any t. Use the heat equation given by ut...

A steel rod 0.450 m long and an aluminum rod 0.250 m long, both with the same diameter, are placed end to end between rigid supports with no initial stress in the rods. The temperature of the rods is now raised by 60.0 ∘C. What is the stress in each rod? (Hint: The length of the combined rod remains the same, but the lengths of the individual rods do not.) Psteel,Paluminium = ?

Two balls of mass 3.29 kg are attached to the ends of a thin rod of negligible mass and length 72 cm. The rod is free to rotate without friction about a horizontal axis through its center. A putty wad of mass 127 g drops onto one of the balls, with a speed 2.5 m/s, and sticks to it. What is the angular speed of the system just after the putty wad hits? 1.31×10-1 rad/s ¡Correcto!

Two 1.9 kg balls are attached to the ends of a thin rod of negligible mass, 62 cm in length. The rod is free to rotate in a vertical plane about a horizontal axis through its center. With the rod initially horizontal as shown, a 0.42 kg wad of wet putty drops onto one of the balls with a speed of 3.2 m/sec and sticks to it. 1) What is the ratio of the magnitude of angular momentum of the...

At 17°C, a rod is exactly 18.08 cm long on a steel ruler. Both the rod and the ruler are placed in an oven at 250°C, where the rod now measures 18.25 cm on the same ruler. What is the coefficient of thermal expansion for the material of which the rod is made? The linear expansion coefficient of steel is 11 x 10-6 1/C°.
