PROBLEM #3 - (25 POINTS) In the motion picture "Jaws", a team is trying to capture a large Great White Shark by attaching three empty barrels to the shark to force it to the surface. However, the team is surprised to learn that the shark can still submerge and swim deep below the surface with three drums attached to it. Please determine the minimum weight of the shark (in pounds) in order to overcome the buoyancy forces of these three barrels and show all work. (Note: 1 Cubic Foot = 7.48 Gallons) Boat Seawater Shark = (Volume 55 cuft) -55 gallon barrel (W=20lbs/ea) PROBLEM #4 - (25 POINTS) Say that you are tasked with determining if a concrete dam was safe to resist hydrostatic loads. Your assessment revealed that your dam is susceptible to overturning and you recommend installing tension anchors at 10 feet on center through the dam and secured into the rock below. To justify this design, please: 1. Sketch a free body diagram of this dam, showing all expected forces. 2. Determine the hydrostatic pressures acting on the dam. 3. Determine the magnitude and resultant of each hydrostatic force. 4. What tension force must the anchors provide if they are to help resist the overturning moments with with a factor of safety of at least 2.0? Water Water Depth = 26 feet -Assume the weight is 30kips per foot of the dam and this is it's center of gravity. 22 feet Embed Depth = 4 feet Dam Width = 30 feet J Anchor=25 feet Rock Anchor (Spaced 10' on Center) Assumed Groundwater Elevation

A 1.00-kg beaker containing 1.63 kg of oil (density = 916 kg/m3) rests on a scale. A 1.94-kg block of iron is suspended from a spring scale and is completely submerged in the oil (see figure below). Find the equilibrium readings of both scales. top scale N bottom scale N

< The mass of a piece of ice is 0.850 kg. density of water = 1.00 x 103 kg/m3, and density of ice = 917 kg/m3. 2. What is the buoyant force on the ice floating freely in liquid water? Enter a positive answer if the buoyant force is upward and a negative answer if the buoyant force is downward. N Question 2 (of 8)

28. A 6.00 [kg] aluminum metal is suspended in a rope and partially immersed in water (Pwater = 1000 [kg/m3]). If the tension in the rope is 4.55 [N], what volume of aluminum was immersed? -3 A. 5.54 x 10-3 [m3] C. 5.54 [m3] B. 6.46 ×ばつ 10−3 [m3] D. 6.46 [m3]

The gravitational force exerted on a solid object is 5.25 N as measured when the object is suspended from a spring scale as in Figure a. When the suspended object is submerged in water, the scale reads 3.98 N (Figure b). Find the density of the object. kg/m3 Scale B MgV

Over the summer I decide to supplement my income educational offerings by building a glass-bottomed boat to drive around Lake Michigan. The glass floor is a rectangle, two meter by three meters, and that floor lies one meter below the water's surface. What additional force pushes up on the glass floor due to the increased gauge pressure underwater? a 10,000 N b 40,000 N c 60,000 N d 120,000N

Can i get help with these questions

Bowling balls are roughly the same size but come in a variety of weights. Given that the official radius a bowling ball should have is roughly 0.111 m, calculate the weight of the heaviest bowling ball that will float in a fluid of density 1.100 ×ばつ 10° kg/m3. weight: N

A chemistry graduate student is designing a pressure vessel for an experiment. The vessel will contain gases at pressures up to 150.0 MPa. The student's design calls for an observation port on the side of the vessel (see diagram below). The bolts that hold the cover of this port onto the vessel can safely withstand a force of 2.80 MN.
