A mechanic is a person who repairs an object which has many spare parts.
How do you you convert 16 of an inch from an architectural scale to an engineering scale?
1/16 convert to engineering scale, 1 divided by 16 = 0.0625" 0.0625" (architectural) divided by (12 in/feet) (to convert to engineering scale) = 0.0052" in engineering scale
Smart houses are works-in-progress allowing centralized computers to control such aspects as lighting, climate control, and appliances. Some features would include timing of lights and remembering of dimming preferences, temperaure and humidity management, and automated control over cooking and laundry. Of course, the home owner would have complete control over all of these processes through access to a main console, which could also be controllable via the Internet.
Why is it that that concrete is stronger at bottom of column than on top?
when concrete is vibrated while pouring in to the form work, the cement slurry part tends to get drained through voids between aggregates and the richest part of cement slurry is detained at bottom portion of column. this causes a strong, dense, and void free concrete which ensures better compressive strength than the concrete on top portion of column.
What is the standard dead load of an elevator in kN?
The standard dead load of an elevator is about 450 pounds. This translates to a kN value of around 0.75.
Importance of steel as engineering material?
steel is one of the most important engineering materials on earth
What is the function of flyash in cement?
Functions of fly ash in cement,
- It is used as a replacement material.
- Low heat of hydration
- Gains strength more than that of the ordinary cement.
How do you calculate the galvanized steel round pipes?
You need to know the thickness of the chequered plate to calculate weight.
As a thumbrule, for 12mm thick chequered plate, you can consider 10 kg per sq.ft. Multiply by area to get the total weight.
+++
You cannot mix units like that. You give the dimensions in mm and kg then introduce feet - it should be all Imperial or all metric.
What are the different waterproofing techniques?
chemical w.p.
bituminous w.p.
brickbat coba w.p.
etc....
How many aluminum beer cans are needed to make an airplane?
I found one statement that a 747-400 has 147,000 pounds of high-strength aluminum.
It takes about 32 empty beer cans to make 1 pound. So 32 cans x 147,000 pounds = 4,704,000 cans. (4 million 704 thousand)
That is 784,000 six packs or 196,000 cases. I drink about 6 beers a day. I think it would take me 2,148 years to go through enough cans to get the 147,000 pounds.
How can you control the flow of traffic at any intersection?
Change it to a large circular roundabout
What is meant by compression joint?
Compression joint is a term typically used in construction. It's a bell and spigot joint that becomes watertight when the spigot is pressed into a compression gasket in the bell.
This all depends on the mix you want. I assume you mean cement when you mention the 80lb bag of concrete.
I have pushed concrete in my day... Bag cement mix is the same as concrete. Don't be funny. How many 80 pound bags will make 1 yard of concrete? I want a definitive answer this time.
This should be in the sexual category. Please look there or simply google full beaver.
How much time does it take to drain an elevated water tank through a 14 inch pipe by gravity?
More info is needed.
What is the elevation of the bottom of the tank relative to the outlet of the 14" pipe?
How much liquid is in the tank, and what are the tank dimensions?
What is the shape of the tank (cone, vertical, horizontal, sphere?)
How many fittings (elbows, turns, half-open valves etc.) are along the length of the pipe?
How much pressure is being applied to the surface of the liquid in the tank or is it open to the atmosphere?
Try this formula for a vertical tank with straight sides open to the atmosphere:
t = pi * D2 / Cd / A *sqrt (h / 8 / G)
where
t = time in seconds
pi = 3.14
D = tank diameter (feet)
Cd = orifice coefficient (use 0.61 for a sharp edge orifice)
A = cross-sectional area of outlet pipe (square feet; A = pi * pipe diameter2 / 4)
h = height of liquid in tank plus height of bottom of tank above pipe outlet (feet)
G = gravitational acceleration (32.2 ft/sec2)
How do you calculate the invert elevation of a manhole?
Invert elevations can usually be found directly on as-built drawings of the sewer facility. The simplest way to calculate an invert elevation of a manhole is to measure the depth of the manhole from the surface to the pipe invert. The invert elevation equals the ground or rim elevation minus this depth.
If you do not know the rim elevation or invert elevation, a surveyor must measure the invert and/or rim elevation with reference to a nearby elevation benchmark (see: http://commons.wikimedia.org/wiki/Image:Elevation_Benchmark.jpg). Also, upstream and downstream invert elevations in a manhole typically differ by about 0.1 feet.
One assumes this is a colloquial term for tunnel advances made by burning torches or other pyro elastic means. among other things the fire hazard is severe, thus the practice is rarely used. it was called Spalling for some reason in US tunnel usage- Railroad tunnel work, here , not mining. It had all sorts of hazards including deterioration of the roof arch.
Advantages and disadvatages of water DAM?
Advantages of dams:
- Dams are constructed based only on safety
- It is used to store water
- It used in hydroelectric power generation
- It is used in irrigation purposes.
- Requires skilled labour to construct
- Strong abutments is needed.
Singly reinforced beam definition?
singly reinforcement beam have steel provided only one side tension an another side compression. tension takes steel load or tensile load and compression takes concrete or compressive load.
Boxed eaves including a boxed gable. a raked eaves concealed or boxed gutter
Significance of grain size analysis?
grain size analysis is used to accertain the various sizes that are available in a particular sample of soil since it is required to calculate the strenght of concrete mix and also the king of soil that the sample is.
