Hi any help with thsi question would be great as im struggling a bit - the final answer should be a) 2.413 MN in the negative x-direction and b)6.97MN Any notes on the method next to calcs would be much appreciated. Thankyou! a)Find the net resultant horizontal force on the wall if it is 10m long (into page), the density of seawater p= 1025 kg/m3, acceleration due to gravity = 9.81m/s2 h1=4m and h2=8m b) find the net resultant vertical force when the density of the wall p=2400kg/m3. The wall is 10m long (into the page), g=9.81 h1=8m and h2=8m
In the United States, electricity is sold using the SI units of kilowatt (kW) or megawatt (MW), and fuel for power generation stations is generally purchased using English units, e.g., British thermal unit (Btu), gallon (gal), and ton. An industrial power plant has an average annual load of 100 MW (electrical). If the overall thermal efficiency is 33% (based on HHV), what is the annual cost of fuel if the plant is fired with (a) natural gas, (b) No. 2 fuel oil, and (c) bituminous coal? Use the data from Tables 2.2, 2.7, and 2.13. Assume the cost of natural gas is $5/million Btu, the cost of No. 2 fuel oil is $3/gal, and the cost of bituminous coal is $60/ton (1 ton = 2000 lbm)
A commpon way of salvaging cannons from old wreacks is to attach an inflatable balloon filed with air. Assume that the cannon is a solid cylinder of iron which is 1.30m long with a radius 17.3cm. The density of iron is 7.87g/cm^3. a. If an air bag were filled twice the volume necessary, what will be the tension in the rope between the air bag and the cannon when the air bag reaches the surface and comes to rest? What volume of air bag wil be floating above the water surface?
nOn 23 January 1960, Jacques Piccard (son of the boat's designer Auguste Piccard) and US Navy Lieutenant Don Walsh achieved the goal of Project Nekton. nThe Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe, reached a record maximum depth of 35,797 ft, in the deepest known part of the Earth's oceans, the Challenger Deep, in the Mariana Trench near Guam in the Pacific Ocean. Taking the density of seawater as 64 lbm/ft3, find the sea pressure in psig at the dive depth

According to the U.S. Geological survey, the volume of water in oceans, seas, and bays is 1.41 ✕ 1018 m3. The average concentration of naturally occurring uranium in seawater is 3.15 ✕ 10−6 kg/m3. If 0.670% of naturally occurring uranium is the fissionable isotope U-235 and each fission reaction yields 200 MeV, estimate the amount of time the uranium in the seawater on the planet could meet the planet's energy needs at an average usage of 1.94 ✕ 1013 J/s.
7. Saul ascends from the city of Tucson, Arizona to the top of Kitt Peak, 2900 m above the sea level. Usually, Saul will feel his ears “pop” as the pressure inside his ears attempts to maintain the equilibrium with the surrounding air. However, on this day Saul has cold and his Eustachian tube is clogged, causing a tremendous pressure behind his 4.0×10^(-5) m^2 ear drum. What force does Saul feel pushing on his ears? (D_air=1.20 kg/m^3) a. 0.50 N b. 0.05 N c. 0.12 N d. 0.08 N e. None of the above

In the design of a jet engine part, the designer has a choice ofspecifying either an aluminium alloy casting or a steel casting. Either materialwill provide equal service, but the aluminium casting will weigh 1.2 kg ascompared with 1.35 kg for the steel casting.The aluminium can be cast for $ 80.00 per kg. and the steel one for$ 35.00 per kg. The cost of machining per unit is $ 150.00 for aluminiumand $ 170.00 for steel. Every kilogram of excess weight is associated witha penalty of $ 1,300 due to increased fuel consumption. Which materialshould be specified and what is the economic advantage of the selection perunit?
If you put a uniform block at the edge of a table, the center of the block must be over the table for the block not to fall off. (a) If you stack two identical blocks at the table edge, the center of the top block must be over the bottom block, and the center of gravity of the two blocks together must be over the table. In terms of the length L of each block, what is the maximum overhang possible? (b) Repeat part (a) for three identical blocks and for four identical blocks. (c) Is it possible to make a stack of blocks such that the uppermost block is not directly over the table at all? How many blocks would it take to do this? (Try.)

The air exerts dissipative effect F = −6πηv on each sphere, where η is the viscosity of the air and v is the linear velocity of each sphere. If I0 = 25MR2 is the moment of inertia of a sphere with respect to its center of mass (image 1)determine the equation of motion of the pendulum. (image 2)
In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .
