2. An 8 foot long aluminum I-Beam with a cross sectional area of 24 in² is placed between two walls when it is at a temperature of dry ice (-110°F). At this temperature the beam contacts both walls, but there is zero force between the beam and the walls. The beam and its surroundings are then heated to room temperature (75°F), (a) Determine the force the walls exert on the beam as a result of this temperature change. (b) Determine the axial stress in the beam as a result of this temperature change. (c) If the beam was not constrained by the walls, what would be its change in length? 국 8 ft

**101. An insulated container is partly filled with oil. The lid of the con- tainer is removed, 0.125 kg of water heated to 90.0 °C is poured in, and the lid is replaced. As the water and the oil reach equilibrium, the volume of the oil increases by 1.20 × 10-³ m³. The density of the oil is 924 kg/m², its specific heat capacity is 1970 J/(kg · C°), and its coefficient of volume expansion is 721 × 10-6 (C°)-!. What is the temperature when the oil and the water reach equilibrium?
Two weights are hung over two frictionless pulleys that are connected by a wire rope to a 500 Ib horizontal block that are in between and below them. The wire rope attached to the upper left end of the block and to the left pulley is at 45 degrees with the horizontal and the wire rope that connects the upper right end of the block to the right pulley is at 30 degrees with the horizontal. If the weight on the left pulley is 50 lb, fs= 0.30 and fk = 0.20 on the surface of block what weight W on the right pulley will cause the 500 lb block to just start moving to the right? *
I need the answer as soon as possible please. Two weights are hung over two frictionless pulleys that are connected by a wire rope to a 500 lb horizontal block that are in between and below them. The wire rope attached to the upper left end of the block and to the left pulley is at 45 degrees with the horizontal and the wire rope that connects the upper right end of the block to the right pulley is at 30 degrees with the horizontal. If the weight on the left pulley is 50 lb, fs = 0.30 and fk= 0.20 on the surface of block what weight W on the right pulley will cause the 500 lb block to just start moving to the right?
The interior contents and materials of a small building weigh 10 tons, and together they have an average specific heat of 0.25 Btu/ (lbm - °F). Neglecting any inefficiency in the furnace, what amount of natural gas must be burned to raise the building's temperature from freezing to 80° F? (Express your answer using three significant figures.) mgan = Ibm
14. A commonly used method of fastening one part to another part iscalled “shrink fi tting.” A steel rod has a diameter of 2.0026 cm, and afl at plate contains a hole whose diameter is 2.0000 cm. The rod is cooledso that it just fi ts into the hole. When the rod warms up, the enormousthermal stress exerted by the plate holds the rod securely to the plate. Byhow many Celsius degrees should the rod be cooled?
You and your team are conducting a restoration project at an old city hall to investigatethe condition of the old chandelier at the main hall. The chandelier was estimated toweigh 4800 N and supported by three cables as shown in Figure 1. The project requiresyou to investigate the condition of the cables holding the chandelier after many years.Given the diameter of cable B is 6mm, while diameter of cable C is 1.25 times and cableA is 1.5 times of cable B, analyze the stress condition of the cables and propose a suitableinclination of the cable B to maintain the normal stress in cable C to be 0.5 times thanthe normal stress of cable B in order for the cable to support the chandelier

PLEASE SOLVE THE FOLLOWING THREE QUESTIONS Question G: Generally speaking, (no numbers required), at what point does Newton's Model of Cooling (T=A+Be^kx) (when regarding dead bodies' temperatures) no longer work? What in reality gives us an indication that we’ve taken it too far? Question H: Assuming that the temperature of the person at the time of death (TOD) was 98.6 °F, set up a TOD equation using the values of ,A, ,B, and k you’ve calculated. Then, solve the equation using the same logarithm method you used to solve for .k. A: 68 Farehneits, B: 17.9 Fareinheit K: -0.002564 TOD: 98.6 Fareinheit Plug the above info into Newton's law of cooling: (T=A+Be^kx) Write your answer as a time, not just as x minutes. Recall that when ,x=0, the time is 2:00 PM. Question I: When forensic expert determines the time of death, they often have additional information besides body temperature. Suppose a coroner finds that the person who was murdered had an infection that probably raised the…
An iron rod at a temperature of 70°F is placed in a room at a constant temperature of 10°F. If after 20 minutes the temperature of the iron rod is 35°F, find (a) the time it will take the bar to reach a temperature of 15°F . (b) the temperature of the bar after 10 minutes.
The heat loss per hour through 1 sq. ft of furnace wall 18" thick is 520 Btu. The temperature on the hot side of the wall is 1900 degrees F, and its average thermal conductivity is 0.61 Btu/hr-ft-°F. Determine the temperature on the other side of the wall in °C.
(a) A piece of unknown metal weighs 184 g. When the metal piece absorbs 482.8 J of heat, its temperature increases from 24.5 °C to 40.9 °C. Determine the specific heat of this metal. 160 QUESTION 14 Continuation of the previous problem (b) Taking this same piece of metal, if it starts at 40.9°C, and is now added to a beaker of water at 23.2°C, you find that the temperature of the water eventually reaches thermal equilibrium at T = 24.66°C. How much water was in the beaker when you added the metal?
