Steel reinforcements are needed at the tension face,so point of contraflexures give us an idea where to bend up/down the bars. However, general practice is to extend the bars beyond the point of contraflexure because we can't predict it accurately (also to account for shear failure).
Shear force and bending moment diagrams of propped cantilever beams?
You can find these diagrams online. A simple image search can help to bring them up and you can choose the one that best meets your needs.
The Haylett Formula is a composite index of labour, materials, plant and fuel. It represents the input costs of building contractors, but does not include contractors' profit margins. From Nicky Day of African Dream Building and Maintenance Services c.c.
Can a slab on grade be a floating slab?
In laymen's terms, yes. Many people use the terms Slab-on-grade & Floating Slab interchangeably.
However, architects, engineers, and construction workers may have a more refined interpretation. Most commonly, a Slab-on-grade construction refers to a foundation in which the a concrete slab (also most commonly thickened at the perimeter) rest directly on grade (aka ground). Where as a Floating Slab foundation refers to a concrete slab resting directly on the grade independently placed within a stem wall (aka foundation wall), which extends down to the depth of the local frost line, running around the entire perimeter. The walls of the building/structure are then built upon this "stem wall". This latter type of construction creates a 'heat bubble' so that the floor is not as subject to the expansion due to frost and secures the structures walls by being supported below the frost line.
What is site operation under building construction project?
a site operation is were you keep a look out on a construction site so many people dont get hurt.
How joint prevent expansion and contraction?
The joint doesn't prevent expansion and contraction but it limits the damage caused by thermal stress. It allows room for the concrete ( or steel ) to expand and contract without creating the severe cracks that would form without them.
What is Most important component to determine the strength of a concrete mix?
The concrete mix should be a 5:1 Cement to water ratio. make sure you mix thoroughly when adding water. Look up "Concrete slump test"
What is all about the stress-strain relation in tension?
When you pull on something, it stretches a bit. Even materials you think are rigid, stretch if enough force is applied. The numbers are very important since they say a lot about the characteristics of materials. Of course all this depends on the thickness of the thing that stretches, so engineers use units that include the cross-sectional area. Strain (Think INch) is the deflection or distance the material stretches.
Stress (Think pRESSure) is the force/cross-section, perhaps PSI.
What is an engineering company?
Engineering and precision engineering companies are companies that design and manufacture products and components. These can range from anything including small precision parts to vehicles etc.
What are laterally restrained beams?
lateral restrain means a restraint provided in the beam to prevent its curving.we can use an I section for that or more than one I sections.
What is the braced column and unbraced column in structural engineering?
column is designed for lateral load it is said to be unbraced column, if not braced column
Will road traffic be reduced by building new roads?
It has not happened that way for the last 1 000 years or so.
More roads means more traffic leads to calls for more roads etc.
Are tractors made from steel bars?
Products made from steel bars include many precision-engineered components that power tractors
How you improve timber lifetime?
there are lots of techniques by which we can improve the life of a timber like seasoning of timber,by applying different types preservatives coat before it is used.
Can you build a pond on top of a house?
Yes it is possible to build a pond on top of an house but doing this you must involve a Civil Engineer the walls may have to be thicken and foundations may get bigger.
Just an architectural hint a glass(actually i think its perspex) pool is nice :)
How can create concrete septic tank?
If your living arrangement is not near a group sewer system, you may require a septic tank and a horizontal seepage system to handle your family unit sewage. Pre-thrown cement septic tanks are promptly accessible, yet conveyance and setup are extravagant. If your neighborhood construction regulations permit it, you may pour your own septic tank on location.

Where is the tallahatchie bridge?
The Tallahatchie Bridge mentioned in the song "Ode to Billie Joe" was in Money, MS (about 10 miles north of Greenwood, MS). This is the bridge that Bobbie Gentry was crossing in the 11/10/1967 LIFE Magazine article (P. 99). It collapsed on 06/19/1972, supposedly after it was set afire by vandals (according to Wikipedia). It was replaced by the current concrete bridge. Here's an article about the original bridge's collapse:
"Money Bridge Collapses, Greenwood Commonwealth, 06/20/1972, P. 1 (with 2 pictures)
MONEY - The TallahatchieRiverBridge here collapsed between 11:30 and midnight Monday and presumably joined Billy Joe MacAllister in the muddy waters of the Tallahatchie.
Leflore County Deputy Sheriff Ricky Banks said he received a call from Sheriff Rufus Freeman about 12:15 a.m. today telling him the bridge had collapsed.
Leflore County Second District Supervisor Ray Tribble had called Sheriff Freeman earlier when two boys who had been fishing discovered the bridge had collapsed. The two boys reportedly had gone upstream to fish and upon returning to Money found they couldn't get over the collapsed span in the Tallahatchie River.
Tribble and his county road foreman Homer Hawkins then blocked the bridge off at the approaches on each side to prevent anyone from driving into the river."
"[Caption under photos] - BRIDGE OUT AT MONEY - The middle section of the Tallahatchie river bridge at Money tilted towards its upstream side as it collapsed Monday night. The steel suspension bridge was built in 1927. Staff Photos by Steve Bailey. "
The bridge used in the movie "Ode to Billy Joe" did not cross the Tallahatchie River. It was located at Rising Sun, MS (about 10 miles south of Greenwood on the Yazoo River (Old Roebuck Road and CR 512). About 2 miles north of Greenwood (South of the original bridge), the Tallahatchie River and the Yalobusha River join to form the Yazoo River. The movie bridge was demolished in 1987 and replaced with the current concrete bridge.
Also note: The song never mentions that Billy Joe DIED. It just says that he jumped off the Tallahatchie Bridge. Jumping off the original bridge from the song, however, would impale the jumper, as the waters are filled with sharp rocks.
The movie depicts Billy Joe's body being pulled from the water from the north side of the movie bridge (Yazoo River). The movie flaw here is that, if Billy Joe drowned, his body would have floated upstream (against the current).
What is the full form of Crs-related to engineering drawing?
It refers to "centres".
When appended to a dimension it means the dimension is to / from the centre mark of a diameter / radius.
