(20 points) A water truck's tank has internal dimensions of 12 meters in length and 1 meters in diameter. If the truck's load of pure water is 70 percent of full capacity, how heavy is the load in pounds? Water's density is 62.4 lb/ft3 lbs In kilograms, what is the weight of the load if the truck carries liquid nitrogen instead of water? The liquid nitrogen's density is 0.808 g/ml. kg

Problem 4. A water reservoir is open at the top, and has radius r 50 ft and wall thickness t 10 in. what height h of the water will produce a circumferential (hoop) stress of 700 psi in the wall of the reservoir? What is the longitudinal (i.e. axial) stress in the wall due to the water? HINT: Water has a weight density of 62 lb/ft3 (so the pressure is caused by the weight of water), and the reservoir is...

1. An ingot is made out unknown quantities of copper (9000 kg/m2) and iron (8000 kg/m). The ingot's weight in air is 82 lbs. If weighed in water, it is only 72 lbs. Find the fraction of its total volume that is iron, assuming the alloy conserves volume during formation. 2. Find the angular acceleration of a 0.3 kg solid sphere with a h-meter radius on...

Question 1 A turning operation is carried out on aluminum. Based on the specific energy values in Table 20.2, determine material removal rate and cutting power in the operation under the following sets of cutting conditions: (a) Cutting speed 5.6 m/s, feed 0.25 mm/rev, and depth of cut 2.0 mm; and (b) cutting speed- 1.3 m/s, feed 0.75 mm/rev, and depth 4.0 mm. Question 2 Consider a turning operation performed on steel whose hardness 225 HB at a cutting speed...
