119 Civil Engineering Questions And Answers
82⟩ What are the materials used in building a gravity dam?
There are many gravity dams constructed of comPActed earth. High dams are generally concrete. All dams require a spillway to be safe. The spillway must be armored.
83⟩ What is the formula for figuring out how many gallons of water are in a pipe by the foot?
0.61 * d2, where d is the diameter of the pipe in inches.
84⟩ Can a wave happen in the middle of the ocean like in the movie Poseidon 2006?
Yes. Rogue waves have been known to capsize ships.
85⟩ What is the tensile strength of marble?
Tensile Strength, Ultimate 7.00 - 20.0 MPA 1020 - 2900 PSI
this is the strength in a pure tension test. For bending use:
Modulus of Rupture 0.00410 - 0.0276 GPA 0.595 - 4.00 ksi
86⟩ What is the density of most of construction materials?
If it floats it is less dense than water, 62.4 lbs/cubic ft. Wood is about 40 lbs/ cu.ft.--it floats. Concrete is 150 lbs. / cu.ft. -- It does not float.
87⟩ What does civil status mean?
Civil means like, when you do not get on with someone, but only talk when you have to. Alternatively, when you do talk you do not argue. Alternatively, if you are with someone who is of your both friends and family, you do not ruin it for them.
88⟩ What is the withdrawal force of steel nails?
In engineering, the code-allowable withdrawal force is zero, because the wood exPAnds and contracts over time and the nail pullout force can reduce to zero.
89⟩ How and where are aqueducts built?
Aqueducts are built in areas where you have a bunch of motivated end users (like a town or group of farmers) at a low elevation in need of a more reliable source of water located somewhere fairly nearby at a higher elevation. The aqueduct builders construct a series of canals, elevated channels, and tunnels as required to get the water from the source to the end users. Some good examples:
a) Roman engineers built aqueducts throughout Italy and France from mountain water sources to serve city dwellers
b) Water-needy Southern California cities and farms are served by an aqueduct that brings them water from sources in Northern California
c) New York City is supplied by an aqueduct and tunnel system from sources upstate.
d) Inca farmers in coastal valleys built irrigation aqueducts from sources higher up in the Rockies
e) Native American cultures in Phoenix area built irrigation canal systems that diverted water from sources at higher elevations to irrigate their crops.
90⟩ What is unit weight of normal concrete?
145 PCF
91⟩ What materials were used to build the Golden Gate Bridge?
Its materials were steel and concrete.
92⟩ Did any of the Egyptian pyramids ever fall down?
Yes, many did. The great pyramid and others that have survived did so for a reason. Their shapes made them sturdier over time and were not the first design. Many steppe pyramids were built but were too steep and as the corners eroded, the whole pyramid fell under its own weight. They were built too steep and did not have the base structure as seen in the great pyramid.
93⟩ Explain the various stages of the project planning process in construction.
First stage could be Briefing and Inception.
94⟩ How do you measure water flowing through 300mm diameter pipes?
Same as in inches 3.14159265 and PSI have to be known.
95⟩ What are the advantages and disadvantages of lead products in construction?
Disadvantages: -Lead is very toxic; its use can result in pollution of the ground and more importantly of water supplies. This leads to the contamination of drinking water and can cause hazards to human health as well as disrupting entire ecosystems.
Advantages: Because of its toxicity, lead is being bought less and less around the world, which of course results in the lowering of its cost. In addition, lead melts at a relatively low temperature, making it great for solder. However, recently the Chinese have show an interest in buying mass quantities to manufacture batteries made from a base of lead so the price of this metal may soon rise.
96⟩ How much does the leaning tower of Pisa lean?
About 14 feet
97⟩ Explain Creep?
bend cause if load act over the beam
98⟩ What in bending moment, if a moment is free end of cantilever beam?
A bending moment is the reaction induced in a structural element when an external force or moment is applied to the element causing the element to bend.
in the free end of cantilever beam the moment should be maximum, and the middle of simply supported beam BM will be maximum.
99⟩ Which purpose we use deck anchor in bridges?
100⟩ How much quantity water should be placed in one cubic meter area?
1000 litres in 1 cum
