1. Which amongst these is stronger hollow steel pipe or a solid steel rod?
On a per pound premise, steel pipe is considered stronger in terms of bending and there are fewer chances of it to buckle in axial compression.
2. What is braced excavation concerned with?
Excavations are propped to avoid the cave-in of encompassing unsteady soil.
3. Which is the world’s longest concrete dam?
The Grand Coulee Dam is considered to be the biggest concrete dam. At present, the world’s largest concrete dam is the Itaipu Dam, an achievement of two neighboring nations, Brazil and Paraguay in South America.
In spite of the fact that it isn’t done yet, the Three Gorges (or Sandapong) Dam on the Yangtze River in China will become the biggest upon its completion.
4. How are the freeway bridges constructed?
The traffic that is probably going to go over the bridge at once is assessed and the cement, shook with rebar stanchions is set over the freeway for bridge construction. The off-ramp from the freeway to the bridge and on-ramp from the bridge to the road are built. Cement slabs are utilized to construct a platform.
5. Why are steel plates included inside bearings in elastomeric bearings?
Keeping in mind the end goal to make an elastomeric bearing act/work as a delicate spring it ought to be made to enable it to swell along the side and furthermore the stiffness compression can be expanded by essentially expanding the limiting measure of the lateral protruding. In many cases, keeping in mind the end goal to expand the compression stiffness of the bearing the use of metal plates is made. When steel plates are incorporated into the bearings the freedom of the bulge is restricted significantly, likewise, the diversion of the bearing is decreased when contrasted with a bearing minus the existence of steel plates. The tensile stresses of the bearings are instigated into the steel plates. However, the existence of the metal plates does not influence the shear stiffness of the bearings.
