Civil Engineering

Khurra is the a depressed place just before the outlet of rain water pipe. The water flowing from the roof moves towards khurra and flush out from the roof through rain water pipe. This is generally 45cm x 45cm in size. It is constructed as under:-

1. First one 400 micron thick PVC sheet of 100cm x 100cm size is laid over the roof slab.

2. Then 50mm average thick 1:2:4 mix cement concrete is laid over the PVC sheet.

3.The top is finished with 12mm thick cement plaster of mix 1:3 and a coat of neat cement, rounded edges and adding waterproofing compound.

You can tell if a spiral spring pitch is normal by this equation; 0.2*D < p < 0.4*D. However, you can calculate a spiral spring pitch by l = πDn, A = πd2 /4.

Weight is 1.579 kg/m

ST 4 concrete is the stronger out of the two. ST4 is equivalent of 16 kn at 28 day strength where as ST2 is only 8 kn at 28 day strength.

I've recently graduated with my BS in Civil &Environmental Eng and I can vouch that it has definitely tough to get a job now. I graduated with a 3.2 gpa, have had 2 internships while in school and worked for a contractor after I graduated only to be laid off shortly after due to budget restraints and a lack of business within the company. I even know of classmates who graduated a year before me and are still looking for jobs. This is not to say that it is a field that is not in demand, but as in any recession the first sectors to feel the economic effects are large scale developments and investments. When investors and municipalities don't invest civil engineers don't have work. However, the economy is bound to rebound out of this recession and once people gain confidence to make big investments we will be back in demand in the market. Also, It is a widely known fact within the industry that the infrastructure of our nation needs to be rebuild, since much of it was first constructed more than 50 years ago. I would say to just study whatever it is that interests you the most and your passion and motivation in that field will bring the jobs coming. Personally, I will be using this time off to go back to school and get my Masters.

Because ppc is most capacity of resist of heat

The grade in cement mainly defile the average compressive strength after 28 days in mega pascals (Mpa) of at least three mortar cubes (area of face 50 cm squared) composed of one part cement, 3 parts of standard s and (conforming to IS 650:1966) by mass and P/4 (P is the percentage of water required to produce a paste of standard consistency as per IS standard) + 3 percentage (of combined mass of cement plus sand) of water, prepared, stored and tested in the manner described in methods of physical test for hydraulic cement.

721 hr not < 23 MPa for 43 grade, 27 MPa for 53 grade

1682 hrs not <33MPa for 43 grade, 37MPa for 53 grade

6724 hrs not <43MPa for 43 grade, 53 MPa for 53 grade

"kN.m is a unit of bending moment.

kN/m is a unit of udl (uniformly distributed load)

as far as i know, there isn't kN.m2 but there is kN/m2

kN/m2 is a unit of pressure acting on an area.

Please check your question again."

I think you have misunderstood the question. The asker can correct me if i'm wrong but I think they mean, for example, that if you have a uniformly distributed load over an floor area in kN/m2 and you have say a beam running across this floor that you would like to run an analysis on, what would be the value of the load in kN/m on the beam?

would it simply be the same value in kN/m or would the conversion affect the value? I say this because I'd also like to know the answer :)

Yes, the characterisrtic strength of a concrete is the same as the compressive strength

Yes. You would need to drive pilings i.e., creosote treated timber or steel into the earth until you hit refusal (by hitting hard pan, shale, rock, etc.) You can determine the required depth needed to drive the piles by first experimenting using a truck mounted geotechnical drill rig equipped with an auger. Once you have determined the depth of refusal (or near refusal) of the soil using a drill rig equipped with an auger then you would need to have a professional engineer make calculations for you to provide you with the number of piles needed and this is based upon the loads of your building. Basically, the piles retain the skin friction against the soils therefore the correct diameter of the piles needs to be calculated by your professional engineer. A pile cap (or grade beam) would be placed over the piles to spread the load of your building across the foundation. Regards, Jerry Tucker, easttexasgeotech@yahoo.com

Sixty specimens each were made of type III and type IV dental stone (Excalibur). Compressive strength of both types of stones significantly (P<.001).

Because we need it to eat food

Soil consistency is an important factor both in water holding capacity as well as water movement through the soil for use by plants. At a fundamental level, soil of such makeup and consistency as to have high field capacity (to retain water in large supply but not oversupply) can support greatest plant (including crop) growth and "fruit" production for use as feed by both wild and domestic animal species. Conversely (for example), soils of poor consistency such as, for instance, desert sand seas or pavements, have as a result only sparse or nonexistent vegetation, and hence support very low animal populations, if any.

A supported beam has both ends of the beam resting on a support. A cantilever has a single support often hinged close to or at one end with the other end supported in another manner.

I think you are talking about embedding steel rods (rebars) in concrete, right? This would make the concrete much stronger. It is called reinforced concrete, and you can make all sorts of structures with it, something that you can't do with ordinary concrete. Though, I am not even sure anyone is using non-reinforced concrete nowadays.

Yes

Because it is strong enough to keep the sheave wheel in place

The reinforced concrete construction is the construction joint in water retaining structure.

1) weight of cement in one cube divided by density of cement = volume of cement in a cube:

2) Similarly volume of fine & Coarse aggregate can be calculated

3) Adding all one will get volume of solids in a Cube-Vs:

4) Subtracting Vs from volume of cube Vc one would get volume of voids Vv

5) taking ratio of Vv to Vs one would get void ratio

A plinth is usually a small column or narrow upright box , used to display art, mostly sculpture. A hollow plinth would have a space in the center, but there are also solid plinths.

The WEF foundation or World Economic Forum is a non-profit foundation commited to improving the state of the world by engaging business, political, academic and other leaders of society to shape global, regional and industry agendas.

No parts of a pig are made of concrete. A pig is an animal made of flesh and blood the same as all other animals. Concrete is a type of wet sand mix that is used to pave sidewalks and make building blocks.

A sense that the language has texture.

Reinforcement designed to resist shear or diagonal tension stresses.
