The thin layer between bark and sapwood from which new wood cells are formed each year is the:
सही उत्तर: ख) Cambium layer
The cambium layer produces new wood and bark cells, forming annual rings.

-
Which type of steel shows a well-defined yield point on its stress-strain curve?
सही उत्तर: ग) Mild steel
Mild steel has a distinct yield point; cold-worked and high-strength steels do not, so a 0.2% proof stress is used for them.

-
Softwoods such as pine and deodar come from trees which are generally:
सही उत्तर: ख) Coniferous (needle-leaved)
Softwoods come from conifers with needle-like leaves; hardwoods come from broad-leaved trees.

The time-dependent increase in strain of concrete under a sustained constant load is called:
सही उत्तर: घ) Creep
Creep is the gradual increase in deformation under sustained stress; shrinkage occurs even without load.

-
The term TMT in TMT reinforcement bars stands for:
सही उत्तर: घ) Thermo-Mechanically Treated
TMT bars are thermo-mechanically treated: quenched and self-tempered to give a hard outer layer and ductile core.

-
Superplasticisers are used in concrete mainly to:
सही उत्तर: क) Greatly increase workability or allow a large reduction in water content
Superplasticisers (high-range water reducers) increase workability or permit lower water-cement ratio for higher strength.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Which admixture is most useful for concreting in hot weather or for long transport times?
सही उत्तर: क) Retarder
Retarders delay setting, maintaining workability in hot weather and during long hauls.

-
Galvanising of steel sheets means coating them with:
सही उत्तर: ख) Zinc
Galvanised iron sheets are coated with zinc, which protects the steel from corrosion.
