A spherical balloon initially having a diameter of 5 in is inflated so that its volume will be twice compared to its original size. At constant pressure, what will be the final temperature of the air in the balloon when T1 = 118°F. a. 1220 0F b. 680 0F c. 660 0F d. 696 0F

7. From measurements taken on the variation of pressure with depth in a liquid, it was found that, on a certain day, 2m below the surface of a given liquid, the absolute pressure was 1.17 x 105N/m², while at a depth of 5m the absolute pressure was 142kN/m². Find a) the relative density of the liquid; b) the atmospheric pressure on the day in question.

Question 3 Calculate the dry rodded unit weight (density), apparent specific gravity, bulk specific gravity oven dry, and bulk specific gravity at SSD for the following two aggregate samples. a) An aggregate sample from a stockpile A has a mass of 35.09 lb. When oven-dried, it has a mass of 33.14 Ib. When brought to a saturated surface dry state it has a mass of 35.18 Ib. When weighed in water, it has a mass of 20.23 lb. A 0.35 ft.³ bucket filled with an oven-dry sample of the aggregate weighs 33.14 lb. b) An aggregate sample from a stockpile A has a mass of 8.93 kg. When oven-dried, it has a mass of 7.4 kg. When brought to a saturated surface dry state it has a mass of 7.87 kg. When weighed in water, it has a mass of 4.35 kg. A 0.009 m.3 bucket filled with an oven- dry sample of the aggregate weighs 13.9 kg.

The pipe assembly of the figure is supported by a fixed support at point A. A couple-moment and a force are applied at points B and C, respectively. In Cartesian coordinates, the applied couple-moment is MB = -150 k N-m, and the applied force is Fc = + 200ĵ Newtons. You may neglect the weight of the pipe assembly. 1. Draw a FBD which is suitable for solution of this problem, when seeking the unknown force and moment reactions at the fixed support, Point A. You may use the existing drawing given below. Your FBD must clearly/correctly show the force and moment reaction vectors. Use double arrowheads to distinguish moment vectors from force vectors. 2. Calculate F°MA, which is the moment generated at A due to the force applied at Point C. 3. Write the equations of equilibrium and solve to find the reactions at Point A. Specifically, find the force-reaction vector, A and the moment-reaction vector, *MA-
