A trough is 7 feet long and 11 foot high. The vertical cross-section of the trough parallel to an end is shaped like the graph of ?=?10y=x10 from ?=−1x=−1 to ?=1x=1. The trough is full of water. Find the amount of work required to empty the trough by pumping the water over the top. Note: The weight of water is 62 pounds per cubic foot. Your answer must include the correct units. (You may enter lbf or lb*ft for ft-lb.)
Exercise #2 A kid is standing with one foot on the top of a PINNED-PINNED COLUMN. 1. What should be the diameter of the column to guarantee the safety of the kid, considering: 1. Kid's weight, W = 30 kg 2. Column length, L = 4 m Metal column with Young modulus, E = 210 GPa 3. 2. Considering the same geometry of the column (i.e., L = 4 m and D calculated from point 1), calculate if the kid...
One cubic foot of water weighs about 62 pounds. To approximate the tsunami that caused the meltdown of the Fukushima nuclear power plant in 2011, a wall of water 45 feet high, 5,280 feet (1 mile) wide, and only 2,640 feet deep would weigh _38,890,368_pounds (write your answer as a whole number; no scientific notation). The largest animal in the world is the blue whale, which weighs about 173 tons (346,000 lbs). The impact of the tsunami from the previous...
The volume of water in large scale reservoirs is often measured in units of an acre-foot, which is the amount of water covering one acre of surface to a depth of one foot. An acre-foot is equivalent to 43,560 ft³. A particular water tower in town was constructed to hold 2.95 acre-feet of water. How many liters of water will it hold? ( 1 US liquid gallon = 231 cubic inches, 3.785 liters = 1 US liquid gallon)
(2,4 A water tank is formed by revolving this graph about It is 4 feet wide and 4 ft high, as shown in the picture. ater is to be pumped to a level one foot above the top, work will be required? Let w be the weight density, in lb per ft", so that your answer will be an expression number the y-axis: It is 4 feet wide and 4 ft high, as shown in the picture. If all the...

18. In the following diagram, a 12-foot slide is attached to a swing set. The slide makes a 65° angle with the swing set. Which answer most closely represents the height of the top of the slide? a. b. e. d. 5.0 feet 5.6 feet 10.9 feet 25.7 feet 19. A 30-foot-long support wire for a 12 foot high streetlight runs from the top corner of a building to a point on the ground, forming a straight line, The length...
Problem 5 You are to examine the retaining wall shown on Figure 2. Assume that the wall height (H) is equal to 12 feet, and the base width (B) is 7 feet. The wall will be approximately 200 feet long (into the page). The backfill material behind the wall is a poorly-graded sand with silt (ŚP-SM) that has an average total unit weight of 1 19 pounds per cubic foot (pcf) and an average water content of 12%. As indicated,...
Calculate the corrected standard penetration test blow count (N1)60 and estimate the soil density using the information given below: Standard Penetration N-value = 15 Test was conducted in coarse granular soil with a safety hammer, 4 inch diameter borehole, standard sampler, and 25 feet of drilling rods. The test was conducted at a depth of 20 feet. The water table was 5 feet below the ground surface. Assume a moist unit weight of 105 pounds per cubic foot above the...
